You can't expect to be the same person you were three years ago. Some people expect you to be and can't come to terms with the fact that if a year has elapsed between LPs, that means one year's worth of changes. The material consequently is affected by that, the lyrics are affected by that... the music too.

Live Aid did feel like one hour's rehearsal after several years, but to be part of Live Aid was wonderful. It reall was.

The key to Zeppelin's longevity has been change.

There's music that can affect people in their lives, and they will always relate to the point that they heard it and experienced it, either if you're playing it or you're receptive, as an audience.

That's the music that I play at home all the time, Joni Mitchell. Court and Spark I love because I'd always hoped that she'd work with a band. But the main thing with Joni is that she's able to look at something that's happened to her, draw back and crystallize the whole situation, then write about it. She brings tears to my eyes, what more can I say? It's bloody eerie. I can relate so much to what she says. "Now old friends are acting strange/They shake their heads/They say I've changed."

Just because you play bass, doesn't mean you have no presence.

There's so much that can be done on the guitar. And that's what is so good about the guitar - everyone can really enjoy themselves on it and have a good time, which is what it's all about.
