It's first time I've seen it too, but I've heard of it... it was a protest about being made to lip sync for a TV segment iirc?
Steve/Nicko's singing has sure come along!!! I was surprised to see steve STARTING with a guitar though, and also expected the drums to not be synced so much due to the fact they are still audible without a mic
At least they were all enjoying themselves, don't often see Steve/Bruce smiling that much around each other these days
.... Adrian didn't seem to be joining in though
