All art really does is keep you focused on questions of humanity, and it really is about how do we get on with our maker.

As you get older, the questions come down to about two or three. How long? And what do I do with the time I've got left?

I had to resign myself, many years ago, that I'm not too articulate when it comes to explaining how I feel about things. But my music does it for me, it really does.

I have all the admiration in the world for somebody like Bono, who really puts himself on the line and tries actively to do something about our world situation.

Strangely, some songs you really don't want to write.

These are all personal crises, I'm sure, that I manifest in a song format and project into physical situations. You make little stories up about how you feel. It's as simple as that.
