Time sometimes passes quite quickly.

We went in and recorded exactly where we were at that point in time. I think because of the quality of musicianship of the band has given it the longevity. I thought the music would endure, I didn't think I would.. I always thought I'd be dead by 30 then dead by 40 and on and on. Now I'm 55 so I didn't even die at 50.

Every musician wants to do something which will hold up for a long time, and I guess we did it with 'Stairway to Heaven.'

The only way to have time is to shut down and then do what you want to do.

Right from the first time we went to America in 1968, Led Zeppelin was a word-of-mouth thing. You can't really compare it to how it is today.

Led Zeppelin was a band that would change things around substantially each time it played... We were becoming tighter and tighter, to the point of telepathy.
