How PSB singles differ (if at all) from the album versions

From time to time I find myself musing, "Now, how is the single of such-and-such Pet Shop Boys song different from the album version?" So I figure the same may be true for you. Here's my attempt to provide a one-stop shop for such questions.

Please note that when I say that a single is "essentially the same as the album version," that means the single and album versions are either absolutely the same or that they differ only in extremely minor, barely noticeable ways, such the single being remastered—as opposed to being remixed—at a louder volume (a common practice) or a difference in length of only a very few seconds. In other cases where I cite more substantive differences in timing, I generally round the figures somewhat to approximations; attempted precision in such cases merely invites disagreements. Besides, official printed timings often disagree with what appears on the digital display of one's CD player or the figure associated with the downloaded file on one's computer.

The songs are listed in chronological order by release date, but please keep in mind that there are regional variations as to when singles are released just as there are as to whether they're released as singles in the first place.

In effect, there is no "album version" unless one counts its appearance (remastered, but otherwise essentially the same mix) on the "Further Listening" disc accompanying the 2001 reissue of Very; the versions that appear on Disco 2 are, like everything else on that album, remixes.

The single is very noticeably remixed from the album version, with additional production and slightly increased length (five or six seconds).

There is no "album version" unless you count its much later re-releases on PopArt and the Bilingual reissue "Further Listening" disc, both of which are essentially identical to the single.

The single is a PSB "remix" that is actually a new recording with Neil's added vocals that incorporates elements of the original from Bowie's album Outside. Radically rearranged, the single is about 50 seconds shorter than the original. When it appeared more than a decade later on Disco 4, it was an extended mix, over two minutes longer.

The single is a shorter edit (by about 25 seconds) of the Bilingual album version.

The single is essentially the same as the album version.

The single is a remix and edit (shorter by almost 20 seconds) of the album version—and, of course, given a new title to avoid confusion with a nearly concurrent single by another artist also titled "Single."

The single is a substantial remix with additional synth lines, particularly toward the end, but shortened from the album version by more than 30 seconds.

Released in the U.S. as a double-A-side with "Se A Vida É," the single is essentially the same as the album version—though, not surprisingly, accompanied by a number of remixes.

A "non-album single" subsequently released in essentially the same form on PopArt.

The single is an edit, shortened by about 40 seconds, of the Nightlife album version.

There are at least three different "single/radio edits" (on different formats and releases and in different locales), ranging in length from nearly a minute to more than 1½ minutes shorter than the album version.

The single is essentially the same as the album version.

There is no "album version."

The single (aka the "Radio Edit") is only about 14 seconds shorter than the version on Robbie Williams's album Rudebox.

The "Radio Edit," which appears on the CD single, is drastically cut from the Nonetheless album version, which is more than two minutes longer. For one thing, the opening and closing instrumental segments are curtailed somewhat. Much more significantly, the bulk of the final third of the album version—largely repetition of motifs and lyrics already heard—has been excised. For instance, the "When you gonna not say no…?" bridge appears three times on the album but only twice in the Radio Edit.
