I think Led Zeppelin must have worn some of the most peculiar clothing that men had ever been seen to wear without cracking a smile.

Of all the failed technologies that litter the onward march of science - steam carriages zeppelins armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.

I don't listen to a lot of new stuff. I just like the old stuff. It's all quite dramatic and atmospheric. You'd have an entire story in song. I never listen to like white music - I couldn't sing you a Zeppelin or Floyd song.

I dabbled in things like Howlin' Wolf Cream and Led Zeppelin but when I heard Son House and Robert Johnson it blew my mind. It was something I'd been missing my whole life. That music made me discard everything else and just get down to the soul and honesty of the blues.

I saw Deep Purple live once and I paid money for it and I thought 'Geez this is ridiculous.' You just see through all that sort of stuff. I never liked those Deep Purples or those sort of things. I always hated it. I always thought it was a poor man's Led Zeppelin.

If you were the first person ever to design an application for the iPhone and you patented it you would be very very better off than we are right now you know? But you've got to be the first one to do it. So I figured that Led Zeppelin or the Stones were going to do it unless we just got on to it. So I got cracking with the guys from Apple.
