There's a lot of sub-conscious stuff you may write but you don't then suddenly sit down and take out your analytical books and say: I'm determined to find out where this came from. You'd probably be wrong anyway.

Let me purify my thoughts and words and deeds that I may be a vehicle for thee.

You take stuff from different places, and sometimes you stick a line in because it rhymes, not because it makes sense.

Once you start to analyze it [Joyous Sound], you've completely lost it. That one just came.

[Rock 'n' roll] music started out with some cat banging a log with a couple of pieces of stick. He sent a message across a river and although the cat on the other side receiving the message didn't know the exact words, he did understand basically something about what was being communicated.

Definitely Muddy Waters has been a prime influence for anybody who's ever done anything rock 'n' roll.

That's the jazz that I like - the stuff that has a soothing effect.
