I'm more lost when I'm not on tour. I'm in a bit of a muddle at nine o'clock - 'Where's the stage?' On tour, there are people directing and supervising you.

Part of my style was getting into a muddle. Audiences think that's part of the act. Sometimes it might be - but you have to guess which bits.

The blues echoes right through into soul, R&B and hip hop. It's part of the make-up of modern music. You can't turn your back on the blues.

I think people are 'just creative,' and this can be expressed in a number of ways. Bob Dylan and David Bowie create both music and art.

We do things on an exchange basis in the music business - it keeps the wheels turning. That's how I can get people like Slash, Flea and Kris Kristofferson on my album. Collaboration should be done through trades rather than charging each other a fortune.

I tried to emulate my favourite guitar players, the old bluesmen like Blind Willie McTell and Big Bill Broonzy. I used to sit by the record player and copy Chuck Berry and the Beatles. You can never copy someone completely, so you end up developing your own style.
