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 How could it become outdated?...We are trying to communicate a fulfilled ideal...I am a reflection of what I sing.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.

Come into my life, here where nothing matters. Come into my life, roll away the gloom.

How much do people really want to learn? I mean, some people get into a groove and they stay with it indefinitely. And what starts off as a great moment of explosive passion can end up as cabaret 25, 30 years later. It just depends on whether you go and find the right habitat to extend yourself.

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.

I wanted my voice to be a tenor sax, really.

Does anyone remember laughter?

There's no point stepping up to the golden platform if you're going to repeat yourself.
