You can put out an album and it could be totally out of the window as far as what you want to do performance-wise.

If it's what you do and you can do it, then you do it.

You learn to read the audiences after a while, and there are all different kinds of gigs.

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.

You have to understand a bit about the poetry of the blues to know where the references are coming from.

Leave your thoughtlessness behind you then you may begin to understand. Clear the emptiness around you with the waving of your hand.

Sometimes you do know where the ideas are coming from and sometimes you don't. You might get a song coming through that you just don't know about.
