Because Led Zeppelin weren't having to worry about doing singles, each time we went in to record, it was a body of work for an album. So you could get the shift and the movement forwards as opposed to having to be rooted back to a single that might have been done a year ago.

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

My influences were the riff-based blues coming from Chicago in the Fifties - Muddy Waters, Howlin' Wolf and Billy Boy Arnold records.

Led Zeppelin was an affair of the heart. Each of the members was important to the sum total of what we were.
