Adding more to this:
When i was in my alice cooper tribute band -- the BIGGEST audience we had, was playing one night in phoenix to almost 800-1000 16-23 y/o screamin' kids. We were shocked so many came, knew the songs and were eating it up. To really rock the place, we ended with Thunderkiss 65. I swear they were gonna jump up on stage any second.
Shocked us, cuz our usual weekend audience at most of our gigs are 30-70 typical drunk old farts who couldn't show enthusiasm if it was sitting on their heads. I think we all can visualize the mental picture.
