I haven't lost my innocence particularly. I'm always ready to pretend I haven't. Yeah, it is a shame in a way.

Possibly the whole creative whirlwind of any musician's life is based on garnering and developing and absorbing more and more experience.

Led Zeppelin has been there through three generations of teenage angst. And there's a generation of kids now who won't know it, post-Linkin Park.

I'm just lucky because my kids are grown-up - I love them, very proud of them, and we are in close contact as big-time friends, but they don't need me that much now and I can actually enjoy this wonderful world of music.

I think I surprise myself.

The essence of my lyrics is the desire for peace and harmony. That's all anyone has ever wanted. How could it become outdated?...We are trying to communicate a fulfilled ideal...I am a reflection of what I sing. Sometimes I have to get serious because the things I've been through are serious...The way I see it, rock n' roll is folk music.

I treat everywhere as being a center from which I can enjoy the surroundings.
