I think the biggest influence for me is when I hear a great piece of music, whatever the style, I'm kind of inspired by that greatness and I'm inspired to try and obtain something that comes close to that greatness.

I never get too many problems. You can never please everyone anyway, obviously. And some people take the easy route and just play the greatest hits, and their audience is happy to hear that as well, and that's fine, but it wouldn't please me. But it doesn't trouble me.

I don't feel old or young, I just am

I've not had Botox, no.

My own personal theory is that all popular music, in whatever form it is, to me, it all comes from Africa. Whether it's filtered through America or whatever - African-American. But I still think there's something in that roots music that's very, very African, and I think that's what unites people.

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

Pop music was supposed to be a flash in the pan, but here we are 50 years later and it means something to us, and it always will do. It's incredibly important.
