If you listen to our work, from 'Led Zeppelin I' to 'Coda,' it's just a fantastic textbook.

I really don't listen to Led Zeppelin that much.

With Led Zeppelin, it has always been that mystique of how the music is done - how it works, why it works.

The Yardbirds folded in 1968, and within a handful of months, Led Zeppelin was not only a band but also a very successful one.

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

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.
