I suppose it's nice to have some surprise in life and to surprise yourself in life and see what else you can do.

You have to keep challenging yourself. I've always tried to do that, and I'm not saying I've always been successful. Maybe I've rewritten the same song; it's inevitable, but I've always been mindful of taking the writing somewhere else. You can't stick in your little comfort zone.

I don't like the royal family, I don't like the establishment, I don't like the civil service.

When I discovered blues - I was 12-years-old - I didn't discover it in America where it was from; I discovered it from Fleetwood Mac - the original Peter Green Fleetwood Mac, Saveloy Brown - like British blues interpretations of it,' which then, when I started the liner notes and seeing all these names, I was like, 'Who's Willie Dixon?' Then I go to the record store and ask the guy there and he goes, 'Oh, you don't know anything.' And so, to me, that's the root of most of it anyway.

I'm not big on rap, to be honest. I just don't get it. It's angry people shouting. I like a song, melodies, people singing.
