If you can get them once, man, get them standing up when they should be sitting down, sweaty when they should be decorous, smile when they should be applauding politely-and I think you sort of switch on their brain, man, so that makes them say: 'Wait a minute, maybe I can do anything.' Whoooooo! It's life. That's what rock and roll is for, turn that switch on, and man, it can all be.
