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 remember one particular occasion when I hadn't played a solo for, quite literally, a couple of months. And I was asked to play a solo on a rock & roll thing. I played it and felt that what I'd done was absolute crap. I was so disgusted with myself that I made my mind up that I had to get out of it. It was messing me right up.

(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.

I guess the solo from 'Achilles Last Stand' is in the same tradition as the solo from 'Stairway to Heaven'...it is on that level to me.

I may not believe in myself, but I believe in what I'm doing.

I know where I'm going musically. I can see my pattern and I'm going much slower than I thought I'd be going.

I don't deal in technique. I deal in emotions.
