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.

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

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

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