Here's a clip that Suefan requested, and Carl sent me: it's Maureen from Zoo dancing to Derek & the Dominos' Layla on Top of the Pops, 18the March 1982.
Notice the early eighties freeze-frame video effects: back them this must have been the height of high-tech cool. Nowadays, when most of us are used to watching video on various phones, computers, laptops, pads, and TVs, transient still frames like this in a video don't mean "cool video effect" any more. These days they say: "connection too slow", "hardware not powerful enough" or "stupid machine not working". How times have changed.
Thanks to carl for the clip.
