In all honesty, I don't know what one song can change.

It's just something internal that says, 'I've got to do this now. This is what I'm doing now.'

The Zombies were really unique - they had elements of jazz and classical music in their songs and songwriting. They had a very, very different sound compared to a lot of their contemporaries at the time.

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

If you're in music, you're in music, and if you're in music you just want to keep making records and playing. That's what it's about, isn't it? At least, that's what I always thought it was about, anyway. I don't think I could bear years and years off. Perhaps in me older, older age, maybe I will, for physical reasons. But to me you've always got to keep proving yourself. I never want to just sit on me laurels. You have to keep forging, to prove yourself to yourself. I always think, every time I start a record, this could be the best thing I've ever done.

The '40s were quite austere and super glamorous.

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