I have an extremely vague memory of seeing something like that on TOTP when I was very young. It's the sort of unusual thing that would have grabbed my attention. Can't Stop from 74 is another one that stuck in the mind because of the traffic lights.

Babs had left by this stage but if your memory is correct it could have been Mary. I remember the band performing but never Pans. I might not have been looking down far enough though and my parents might not have told me so to stop me buying the record. It needs other input.
Everywhere, wherever you look, manipulation rearing it's head.
I thought we'd already cleared this one up by then it might have just been for my benefit. "Do The Bus Stop" on the 15/01/1976 show featured a brief appearance by one or more of the Pans ladies but was not a proper dance routine. Perhaps more than a strongly rhythmic hylobatidae but less than an umbrella adorned sauce.
