1968: No idea who The Alan Bown Set were, but this grainy footage of their number 27 smash and all its psychedelic lighting exists, so here it is.
1985: Mai Tai adopt the three-girl soul template of the 80s, that of three women, one in a leather jacket and short skirt, gyrating endlessly around the same points. Once Janice has plugged the Live Aid book Dan Hartman - "good bloke", apparently - and his own workmanlike band have promoted the two backing singers to level with the frontman on stage. Potentially dangerous. Speaking of which, surely Thompson Twins have far more room than that to move about in. Alannah Currie was busy inventing Bart Simpson.
1991: As Mark Wahlberg's career progresses Marky Mark & The Funky Bunch seems more and more like a fever dream than a man shouting in a bucket hat he surely can't see out of. He then takes his jacket off to reveal himself shirtless off camera. You'd have thought the screams might have alerted the director. Can't work out if Mark Goodier is taking the piss afterwards. The Farm's bassist takes advantage of playback to dart all over the place as Peter Hooton holds that mike aloft and rigid. Tin Machine's gimmick, other than Bowie's presence, turned out to be instruments with tiny bodies and little or no headstocks. Worth a go. Unlike, say, Arnee And The Terminaters. Steve Wright and Richard Easter's fault. And pop culture's, I suppose.
1997: UB40 erect a massive monogrammed wall at the back. None shall pass, unlike with Symposium, though the traffic is going the other way in that case. The concluding stage invasion includes one man, who you'll see at 3:27, who gets up on stage with no great enthusiasm, almost out of civic duty. As if inhabited by the spirit of Dortie, Jayne ploughs gamely through her script as if nothing was going on behind her.
2003: Not so much flying the flag as wrapping it round a stationary object, a Doherty-less The Libertines rouse rabbles with little in the way of conviction, if that isn't a contradiction. Girls Aloud could have done with buying or renting a couple of armchairs along with the sofa.
