I'm still terrified of flying. I really have to get drunk to fly. I've found that I've developed fears I never had before... fears of heights, claustrophobia... only in cities, though, never in the country.

I can listen to all different sorts of music. I don't really care about The Next Big Thing.

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

So far I've been very, very fortunate because it appears that people like to hear the music I like to play. What more fortunate position can a musician be in?

We kept moving forward and didn't try to recreate the past .. the approach to each album was radically different every time. Many bands would have some success and, because they were locked into having a single - something we didn't have to worry about - they had to make sure there was something similar on the next album ... that was never the idea with Led Zeppelin .. the goal was to keep that spark of spontaneity at all times.

I always felt if we were going in to do an album, there should already be a lot of structure already made up so we could get on with that and see what else happened.

My vocation is more in composition really than anything else - building up harmonies using the guitar, orchestrating the guitar like an army, a guitar army.
