1981: Doesn't say much for Bucks Fizz if they have a line of people looking away from them enjoying themselves throughout. Ultravox's Midge Ure tries out the electro-spiv look.
1986: Are jokes funnier upon repeat? Depends on how much extra you put in. Sigue Sigue Sputnik went to town on the hair and costumes and there's less explosions than before. Martin Degville just forgets himself entirely at 1:16.
1987: Here's an odd one. As keen as our hosts are to tell us this is live - three times in the first link - they're clearly in a different, smaller studio with no uncanned audience (the pull shots around John Farnham, the only new performance in the show, give that away). This was the day of the general election so presumably everything else was being used. The first two thirds are available, part one with Farnham and half of the Beastie Boys in Montreaux, part two its second half and Run DMC on location too, plus Tom Jones pulled in for a minute's work during Breakers.
1999: Though they'd make up for it in time, this was Red Hot Chili Peppers' studio debut, Antony Kiedis rocking a shirt/tie/shorts look. At his age. Cher tried to replicate Believe's computer-voice success but the audience were keener on the dancers.
2004: Emma Bunton goes Latin jazz! But has to be showbiz lowered from the rafters regardless.
2006: Welcome Lily Allen to the nation, actively betraying nerves. She also seems to be singing over her own backing track vocals on the choruses. The Automatic demonstrate the various angles guitars can still apparently be played at.
