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.

Well, Led Zeppelin IV! That's it really. I'll tell you why the album had no title - because we were so fed up with the reactions to the third album, that people couldn't understand why that record wasn't a direct continuation of the second album. And then people said we were a hype and all, which was the furthest thing from what we were. So we just said, `let's put out an album with no title at all!' That way, either people like it or they don't... but we still got bad reviews!

Sometimes, I must admit, I'd like to have a second guitarist onstage with me, but it wouldn't look right. I'd like to play for another 20 years, but I don't know... I just can't see it happening. I don't know why. It's a certain foreboding... a funny feeling... vultures.

This week, I'm a gypsy. Maybe next week it'll be glitter rock.

My finger picking is sort of a cross between Pete Seeger, Earl Scruggs, and total incompetence.

There will be a Led Zeppelin as long as there's a Jimmy Page, John Bonham, John Paul Jones and Robert Plant. This isn't a nostalgia band playing the hits forever. If anything ever happened and somebody left - which I really can't see happening - I don't think we'd bother to carry on. The magic for me is as it is now.

I deal in emotions. It's the harmonic side that's important. That's the side I expected to be much further along on than I am now. That just means to say that I've got to keep at it.
