Back Chat (Extended Version) 6:55
Written by John Deacon, Remixed by John Deacon

Queen's first extended/12" mix. Features a lot of extra drums and instrumental parts. Added guitar by Brian at the end is a nice touch. A pretty good mix.

Back Chat (Single Remix) 4:12
Written by John Deacon, Remixed by John Deacon
Appears on: UK Back Chat 7" vinyl, UK The Singles Collection Volume 2
An improvement over the album version. This version cuts out some of the instrumental sections of the album version and remixes together quite nicely. In general, the song sounds much better (much like the Pain Is So Close To Pleasure single remix was better than the album version). This one deserves a CD release. The technically savvy can also rip this from the Queen GVH2 DVD (the video uses the audio from this remix version).

Back Chat (Demo) 4:35
Written by John Deacon
Appears on: Unreleased
A neat demo with a slightly different intro, with a few bass notes that add a bit to the track. The track's lyrics are still early and very different from the final version. Worth a listen just to hear how the song has progressed.

Body Language (Hollywood Records 1991 Remix) 4:44
Written by Freddie Mercury, Remixed by Susan Rogers
Appears on: Hot Space Hollywood Remaster (1991)
Not a bad remix by Hollywood Records. Features some extra guitars and an added back beat. The best part of the remix is the added piano bits. If you like the original, this is worth a listen.

Action This Day (Demo) 3:40
Written by Roger Taylor

Again, not very different from the album take. Freddie's vocals are noticeably different in some places. Roger's backing vocals are much more pronounced (like they are for live versions of this song). Synthesizer and horn solos are present even in this early version.

Life Is Real (Song For Lennon) (Demo) 3:29
Written by Freddie Mercury
Appears on: Unreleased
Amazingly similar to the album version. Freddie's vocals are noticeably different in some places. Track begins with either drum machine or Roger. Brian's guitar work is a bit more drawn out and Freddie's piano has a bit more volume to it.

Calling All Girls (Album Version) 3:52

Appears on: Hot Space, Track 8

Calling All Girls (Live At Siebu Stadium) 4:44
Written by Roger Taylor
Appears on: Queen On Fire: Live At The Bowl DVD
From the Japanese leg of the Hot Space tour, this version is found as an extra on the Queen On Fire: Live At The Bowl DVD, as the music that accompanies the photo gallery. A great, heavier version of the song with an intro by Freddie and an extended ending makes this a keeper.

Cool Cat (Original Version with David Bowie) 3:48
Written by John Deacon/Freddie Mercury
Appears on: Hot Space Test Pressing
Very similar to the album release, but featuring Bowie doing some backing vocals. Bowie's vocals actually add a weird element to the track. Definitely worth finding, although the current bootleg copies are not the best. Hopefully we'll see this on Queen Anthologies.

Under Pressure (Greatest Hits 2 Edit) 3:55
Written by Queen and David Bowie
Appears on: UK Greatest Hits II, UK David Bowie: The Singles
A pointless edit for UK's Greatest Hits II. The only difference is the end lyrics "this is our last dance..." is only repeated once, as opposed to the normal two times.

Under Pressure (Classic Queen Remix) 4:02
Written by Queen and David Bowie
Appears on: US Classic Queen, US David Bowie: The Singles
Again, almost exactly like the album version. The bass lines seem to be a bit more prominent in the mix and the overall sound is a little less muddy. Freddie singing "that's okay!" has been removed right before Bowie sings, "it's the terror of knowing..." A pointless and useless remix.

Under Pressure (Karaoke Version) 3:51
Written by Queen and David Bowie
Appears on: Greatest Karaoke Hits
A nice instrumental version which shows there's much more to this song than people may think. Track ends short of the album version by removing the finger snapping at the end. There is no click track to this karaoke version.

Under Pressure (Rah Mix) 4:08
Written by Queen and David Bowie
Performers: Queen + David Bowie
Appears on: Greatest Hits 3, 1999 Under Pressure 12" vinyl promo, Queen + David Bowie/Elton John CD promo
A really good remix to promote the Greatest Hits 3 release. Features brand new lyrics to open the song from both Bowie and Freddie. The mix is bass heavy and features some neat guitar and vocal effects. This is more of a rock mix and isn't as dance oriented as the Hollywood mixes. A very nice remix that offers something new. Check this out just for the added lyrics at the beginning.

Under Pressure (Rah Mix Edit) 3:53
Written by Queen and David Bowie
Performers: Queen + David Bowie
Appears on: UK Under Pressure Rah Mix CD Single, UK Under Pressure Rah Mix 7" vinyl
This mix is exactly the same as the regular Rah Mix, except that it's missing the 15 seconds of extra vocals from Bowie and Freddie at the beginning. It's a shame that one of the most interesting parts of the song was edited.

Under Pressure (Spencer Mix) 3:52
Written by Queen and David Bowie, Remixed by Mike Spencer
Performers: Queen + David Bowie
Appears on: UK Under Pressure Rah Mix CD Single, Queen + David Bowie/Elton John CD promo
A nice remix that stays true to the original song. The bass line is much more prominent. The song opens with Bowie's backing humming edited in with Freddie's a capella opening. A few effects are added here and there which adds a bit to the song. Not a bad mix at all.

Under Pressure (Knebworth Mix) 4:17
Written by Queen and David Bowie
Performers: Queen + David Bowie
Appears on: UK Under Pressure Rah Mix CD Single
Recorded live at Knebworth Stadium. This live mix from Queen's last concert starts with Freddie doing his vocals exercises with the crowd and goes right into the live version of Under Pressure from that night's concert. Great to have just because this is the band's last performance of the song.

Under Pressure (2000 Club Mix) 5:21
Written by Queen and David Bowie
Performers: Queen + David Bowie
Appears on: 1999 Under Pressure 12" vinyl promo
Track begins with the strange guitar effects from the Rah Mix and pretty much remixes and rearranges the Rah Mix edit from that point on.
