When I was a kid, I wanted to be serious, like Daniel Day-Lewis. No one really dreams of being a comic actor, do they? Now I realise how stupid that is - and it's because comic acting isn't taken seriously enough. It's a discipline. You know instantly - either you're funny and getting the laughs, or you're not.

If you're in pop music, you've got to deal with the changing of the guard every few years. By the time the '70s arrived, I was well aware of the cyclical nature of the game. Pop music is a creature of the moment; it thrives on the mood of its time. Either you hook into that or you're not going to be part of it.
