Taking drugs on a recreation level is one thing. But taking them while you're working on a stage is, I don't think it was that great. It's the control factor. And the thing about being on stage, you really want to feel that you're sort of in control a lot. It's not a place where you want to be out of control.

One song isn't going to ever change things, but I suppose it's the accumulation of music generally [that is]. If you can imagine a world that has no music in it, it would be a very different world, so music does change the world by virtue of all the music in it. Cumulative music of every kind, from banging a drum to playing a flute or recording symphonies, or singing 'War, what is it good for?' All those things change the whole way we live.
