I saw this in the early 1980's, i think as part of Dance Umbrella at The Place in London, though it may have been at the ICA. can't quite remember now. It was knock out then, and still is now. Yes, I am revisiting it because Beyonce has just ripped off bits of its dance style for her video for the song Countdown. Well, I guess its flattering, but this wholesale unacknowledged borrowing is getting to be a habit with Beyonce.
