I'm not a big fan of lead vocalists, people who sing but don't play. I never wanted to be in a band where the guy who was up front just sang. I've always thought it better when one of the musicians sings, like Steve Winwood.

I'd love to knock an audience cold with one note, but what do you do for the rest of the evening?

I feel a real need to observe a level of propriety in what I'm handing out. Instead of me just venting or spilling my guts, I've got to consider how it's going to affect people. How it's going to affect me, as well. Because it's like a cycle.

My definition of Blues is that it's a musical form which is very disciplined and structured coupled with a state of mind, and you can have either of those things but it's the two together that make it what it is. And you need to be a student for one, and a human being for the other, but those things alone don't do it.

Yeah, it is, because it's a real discovery of your inner resources, you know. That's what my character is all about and what my playing is all about. But to get up there and just go inside and draw out something that makes you feel good first and foremost.

I don't have half the nerves there that I have anywhere else.

This moment in time, on this tour, you know, I'm discovering a lot of new things. And to be 45 and doing that, it's a mixture of pleasure and pain, I can assure you.
