Many people think of me as just a riff guitarist, but I think of myself in broader terms. As a musician I think my greatest achievement has been to create unexpected melodies and harmonies within a rock and roll framework. And as a producer I would like to be remembered as someone who was able to sustain a band of unquestionable individual talent, and push it to the forefront during its working career. I think I really captured the best of our output, growth, change and maturity on tape - the multifaceted gem that is Led Zeppelin.

(The Song Remains The Same) is not a great film, but there's no point in making excuses. It's just a reasonably honest statement of where we were at that particular time. It's very difficult for me to watch it now, but I'd like to see it in a year's time just to see how it stands up.

Crowley didn't have a very high opinion of women, and I don't think he was wrong.

I don't feel I have to top myself at all.
