I really enjoy playing America. I like the audiences there. It's the home of a lot of music I grew up with.

When you look at so much of what we all love, there's either soul-based to it, or it's the blues. It's really the beginnings of any kind of music. It really is; it all starts there. Because after that, it's music of the moment.

I look for that stimulation constantly. I'm looking for inspiration and stimulation. Not bored with what we've done.

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 get bored quickly. I kind of take my hat off to bands who have been around for a long time and still do the same thing, because it's hard to keep a band together for decades. But I couldn't do that. I couldn't play the same songs night after night or just trade on my past glories, because it wouldn't interest me as a person.

When I got into the Beatles, I must have only been about six or seven but old enough to take notice. We used to have an old radiogram which, for readers of a certain age, was like a big cabinet thing with a record player inside it.

The Beatles changed the world. They certainly changed my world, and many, many other individuals as well.
