The States were much more fun. L.A. was L.A. It's not L.A. now. L.A. infested with jaded 12-year-olds is not the L.A. that I really dug.

How can you consider flower power outdated? The essence of my lyrics is the desire for peace and harmony. That's all anyone has ever wanted. How could it become outdated?

If you do what you think is right for the benefit of everybody and everything and you make decisions, to go back and regret them afterwards - it's a futile experience and it's not worth thinking about. Because life just unfolds. Provided you do your best and you think you're on the right track, you can only be right or wrong. But to regret it - I don't think there are any huge errors or misdemeanors.

I was young - I was 20 years old. Now I have the gift of perspective and I feel pretty good about it.

Lately, I'm spending more and more time working with non-rock musicians and leaving the mainstream - almost dissolving into another world, musically.

You would find in a lot of Zep stuff that the riff was the juggernaut that careered through and I worked the lyrics around this.

It's sort of a feeling of power onstage. It's really the ability to make people smile, or just to turn them one way or another for that duration of time, and for it to have some effect later on. I don't really think it's power... it's the goodness.
