It's very dependent on your state of mind. And your emotional state as well. And a lot of it comes pouring out, you don't really have that much control with it.

It's been up to me to inspire me.

I remember when I thought of singing as the bit that went between the guitar playing - something I couldn't wait to get out of the way. Singing was originally like a chore that I didn't really enjoy.

It's been very important throughout my career that I've met all the guys I've copied, because at each stage they've said, 'Don't play like me, play like you.'

I tried when I was 13, when my grandparents gave me an acoustic guitar, and I tried for a year. It hurt so much to play. I mean, the fingertips hurt so much, I gave up.

But I did go to music really early on, even when I was 4 or 5, I was responding to music probably in ways other kids were not.

It was stumbling on to really the bible of the blues, you know, and a very powerful drug to be introduced to us and I absorbed it totally, and it changed my complete outlook on music.
