UK 7" [Parlophone R6365]
The UK 7" comes in a glossy card sleeve opening from the side and indented on the back for easier access to the record (view front and back artwork from the menu on the left). The record has a solid centre and vintage black Parlophone labels with silver text and a big Parlophone logo top-left. There's a retro-looking "45RPM" top right, production credits, EMI copyright and publishing info on the left, label code, catalogue numbers, "BIEM/MCPS" and "Made In UK" on the right, track listing including songwriting credits and running time at the bottom above "Morrissey & Siouxsie", and a legal warning around the top edge.

UK 12" [Parlophone 12R6365]
The front artwork of the 12" format is very slightly different to that of the 7" in the cropping of the image and in the position of the text (see left). The back of the sleeve is minimal like the back of the 7", it features the same elements (the barcode, track listing, credits, Parlophone logo) in the same position, but in a relatively different size (view left). Also, the track listing obviously mentions this format's bonus instrumental version of the title track. The record comes inside a white poly-lined paper inner sleeve and bears vintage black Parlophone labels with silver text and a big Parlophone logo top-left. There's a retro-looking "45RPM" top right, production credits and EMI copyright on the left, catalogue numbers, publishing info, label code and "Made In UK" on the right, track listing including songwriting credits and running time at the bottom, and a legal warning around the top edge.

UK cd-single [Parlophone CDR6365]
The cd-single comes in a thin jewelcase. When compared to the other three UK formats, the cd's J-card insert shows a cropped close-up of the usual image (view left). The spine and back are white with black text. The spine states "Morrissey & Siouxsie", the title track and the barcode number. The back flap has on the left a large barcode box including the two catalogue numbers, an empty "F:" compartment, one that states "Printed in UK" and another one with a 3-line manufacturing credit. To the right of the barcode are found the track listing and a sideways Parlophone logo. The insert's reverse was adapted from the 7" and 12" back artwork but there is no barcode on this surface (view left). The disc is black with very pale grey (almost white) text and a Parlophone logo at the top. The track listing on it includes songwriting credits and running times and is found in the bottom half above "Morrissey & Siouxsie". A Compact Disc logo, production credits and an EMI copyright are on the left, the barcode number, publishing info, a label code and "Made In UK" on the right and a legal warning around the top edge.

UK cassette single [Parlophone TCR6365]
The front of the cassette-single shows the same image as the other formats, but it is cropped differently, showing less of the sides and more at the bottom (view left). The spine and back are white with black text and logos. The spine states "Morrissey & Siouxsie" above "Interlude" in the same font as on the front, with a Parlophone logo at the top and the barcode number at the very bottom. The back flap shows a barcode at the centre, between the track listing on its left and logos for Parlophone and Dolby on its right. The barcode box includes 4 sideways compartments on the right: "F:" (left empty), "I:" (left empty), "UK:" which includes the UK catalogue number and a fourth one with two lines of text including "Printed in UK". The insert has one extra fold-out panel. It is white and shows in black the track listing, credits, EMI copyright and Parlophone logo as on the back of the vinyl sleeves and cd insert. The cassette is made of black plastic with pale grey text printed directly onto it. It shows, amongst other things, the barcode number in the top left corner, the track listing top-centre and a Parlophone logo in the top right corner.

UK jukebox 7" [Parlophone R6365]
This item is just like the stock 7" described above but at the centre is a large hole for jukebox play. The record comes in a stock picture sleeve.

UK cd promo [Parlophone CDR6365]
EMI did not go out of their way to promote the release of this single. The only known promotional items were stock cds with plugger and promo stickers affixed respectively on the front and back of the case. Two different variations have been reported. The sticker on the front of the first variation gives the contact information of Parlophone pluggers Deslyn Lewis and Kevin McCabe (information about the text on the release info sticker on the back is needed). The sticker on the front of the other variation gives the contact information of Parlophone plugger Helena McGeough. This variation may not have a release info sticker on the back (confirmation/correction needed).

UK press release
The existence of a press release advertising the release of this single has been reported. It presumably was distributed with copies of the promo cd described above, but this needs to be confirmed. Information about the content of this press release is needed.

UK promo flat
A flat was sent to retail at the time of release of the single. Like most other flats, it is made of card and is the size of a vinyl LP sleeve. This one appears to be one-sided or perhaps looks the same on both sides (confirmation needed). View here.

UK 7" test pressing [Parlophone R6365]
Test pressings for the 7" format have silver injection-moulded 'labels' with nothing printed on them. The silver portion is narrower than the space that would normally be taken by a label and the centre is black. These test pressings are usually found in a white paper record bag with "Morrissey + Siouxsie" and "Interlude" handwritten on it. There is an estimated 8-10 copies of this item in circulation, depending on who you ask.

A few 7" test pressings of "Interlude" with white paper labels have entered the collectors market in 2009. At best, these white labels are presumed to be test pressings of the "Interlude" 7" found inside the boxset "The 7" Singles '91-'95" released that year, or at worst, counterfeits.

UK 12" test pressing [Parlophone 12R6365]
Test pressings of the "Interlude" 12" have white paper labels with nothing printed on them. They are usually found inside a white poly-lined paper record bag on which "Morrissey + Siouxsie" and "Interlude" is handwritten.

UK reference 5" cd-r [Abbey Road]
The top collectible item on this page must be this reference cd-r featuring 10 different versions of "Interlude". Among the 10 versions are found the three released ones, one with Morrissey only vocals (which was eventually released on "The Very Best Of Morrissey"), one with Siouxsie only vocals, some with fewer vocals, and some with alternate instrumentation, etc. Information about the packaging is needed.

UK reference 5" cd-r [Abbey Road]
This alternate Abbey Road reference cd-r features the same material as the stock cd-single. It comes in a custom title Abbey Road studio reference sleeve with Abbey Road logo front top, and typewritten filled sections "ARTIST" (MORRISSEY), "TITLE" ("INTERLUDE - CD SINGLE"), "DATE" (22.11.93) and "CAT NO" (blank). The back shows printed precautions, a warranty and a Transco logo. The track listing including total duration is printed inside. The CD-R bears a Transco logo at the top and has handwritten on its surface the same information as found on the front (artist, date, etc).

UK reference 3" cd-r [Abbey Road]
This very interesting Abbey Road 3" reference cd-r features the same 3 tracks as the final cd-single. It comes in a jewel case specifically designed for this 3" format, a bit like a smaller slimline jewel case with an insert that wraps itself around the pale beige tray and with the "CD Single" logo moulded into one corner of the case's front panel. The front of the generic Abbey Road insert shows a black and yellow Abbey Road logo at the top. Beneath it are four grey boxes filled with printed information. The 'Artist' box has "Morrissey & Siouxie" [sic] printed in it, the 'Title' box has "Interlude", the 'Date' box has "14/6/94" and the "Cat No" box was left empty. There is a Compact Disc logo in the bottom left corner and beneath the line "reference cd by" in the bottom right corner is printed the name "Adam Nunn". The only text on the back flap is an Abbey Road Studios address in London. The back portion of the insert shows four "precautions" to be taken in the care of the cd, with "Made In Japan" in the bottom right corner. The disc is a TDK CD-W08 showing the TDK logo and brand at the bottom. The names of "Morrissey" and "Siouxie" [sic] are handwritten in marker at the top of it.

The existence of an Abbey Road 3" cd-r dated "6/24/94" is rumoured, but this is probably the same as above with the date incorrectly reported.

UK reference cassette [Abbey Road]
This reference cassette served in-house purposes in the making of the single. It features the same three versions of the song found on the cd- and 12" singles. The front of the insert states "Morrissey and Siouxsie" and "Interlude" above the numbered track listing which includes running times, all this in black over the pale grey and yellow Abbey Road logo. The spine repeats the names of Morrissey and Siouxsie and the title, with the black and yellow Abbey Road logo at the bottom. The logo is repeated on the back flap next to the words "Copied in Real Time by Maria Gordon At Abbey Road Studios on 15 June 1994" and the contact numbers for Abbey Road (date to be confirmed). The insert has one extra fold-out panel but it is plain white with nothing printed on it. The cassette is a generic Transco TRII made of smokey transparent plastic. One side (or both?) has a white sticker label showing the black and yellow Abbey Road logo on the left, with "Morrissey and Siouxie" and "Interlude" printed one above the other on the right.

UK reference cassette [Abbey Road]
This other Abbey Road reference cassette is similar to the one above, but it only features the basic 3:48 version of "Interlude". The front has the usual pale grey and yellow Abbey Road logo, but the only text printed over it is "Morrissey & Siouxie" [sic] and "Interlude". The spine repeats the names of Morrissey and "Siouxie", with the black and yellow Abbey Road logo at the bottom. The logo is repeated on the back flap next to the words "Copied in Real Time by Lee Mansfield At Abbey Road Studios on 22 June 1994" and the contact numbers for Abbey Road. The cassette is a generic Transco TRII C-20 made of smokey transparent plastic. One side has a white sticker label showing the black and yellow Abbey Road logo on the left, with "Morrissey and Siouxie" [sic] printed on the right.

UK reference cassette [Abbey Road]
The existence of an Abbey Road reference cassette featuring 10 versions of "Interlude" (just like the reference cd-r described above) has been reported. Confirmation and information on the packaging is needed.

Australia cd-single [EMI Australia 881583-2]
The Australian cd-single differs from the UK one by a few details on the back of the insert and the disc. Just like the UK cd it comes in a slimline jewel case. The front and spine of the insert are perfectly identical and the back differs only in the omission of "Printed in UK" in one of the compartments next to the barcode. Nothing was changed to the track listing and credits on the reverse of the insert. The most striking difference is in the disc which is white with black text instead of black with grey text like its UK and Dutch counterparts. The layout of the text is the same as in the UK and only a few changes were made to it. Just like the UK disc there's a Parlophone logo at the top, a Compact Disc logo, production credits and an EMI copyright on the left, the track listing including songwriting credits and running times in the bottom half above "Morrissey & Siouxsie", and a legal warning around the top edge. Everything on the right side of the disc was removed, leaving only "Stereo", the Australian catalogue number and the logo for Digital Audio Technologies Australia.

Australia cassette single [Parlophone 881583-4]
The Australian cassette-single was manufactured in a card slipcase instead of a standard plastic case with J-card insert. The front of it shows the exact same front artwork as on the UK cassingle. The back is the same as the extra fold-out panel of the insert of the UK cassette, with an additional barcode in the bottom right corner. The spine is white with black text. It shows Morrissey and Siouxsie's names and "Interlude" in the same font and layout as on the front, with a Parlophone logo at the top and the barcode number at the bottom. The cassette is made of transparent plastic, its reels are blue and text is printed in blue directly onto it. "Interlude" and Morrissey & Siouxsie's names are at the top on each side, a Parlophone logo on the left, the catalogue number printed sideways on the right above a Dolby logo.

Holland cd-single [EMI 881583-2]
The Dutch cd-single differs from its UK counterpart by only a few details on the back flap and the disc. Just like the UK cd it comes in a slimline jewel case. The front and spine of the insert are perfectly identical and the back differs only in the presence of a French price code in the "F:" compartment next to the barcode, and in the credit next to it which was changed to "Printed In Holland". Nothing was changed to the track listing and credits on the reverse of the insert. The differences on the disc are the additional "CDR 6365" catalogue number above the barcode number on the right, the switch of the musical rights societies from "BIEM/MCPS" to "BIEM/STEMRA" and the correction of "Made In UK" to "Made In Holland". Also, while the text is very pale grey, almost white on the UK disc, it is mid-grey on some Dutch discs and golden on others.
