I think you can refine what you do, and become more consistent. And you write better songs that have a better shape and a better feeling. You evolve into and out of things, and go through stages, but, ultimately, you do improve.

There is in fact a controversy over Darwin's theory. Clearly both theories have religious implications. But this is not about God.

I'm glad there are a lot of guitar players pursuing technique as diligently as they possibly can, because it leaves this whole other area open to people like me.

As the writer, you're always a presence in the song. If you get close to what human beings are like, you're writing about common experience. We all do much the same things, so if you nail somebody, then you've also nailed yourself.

I think whatever you believe in affects whatever you express, whatever you create. It shapes your morality in some way. But I don't think that's something that you have to shove down people's throats. I'd rather keep it in the background, and I'd rather people came to the music in an unprejudiced way. I'm glad, in a sense, that most people don't know about me, what I do, much. I'd rather they hear the music, and then say, "I wonder what kind of person created this."

Well, first of all it's entertainment. That stops us becoming too pretentious or thinking we're great artists.

The thing I do, really, is a communication with audiences more than any achievement through records.
