Austin - it's a stimulating center. In this conversation, the very first two questions were talking about my kind of wanderlust and my adventures. Some people at my time in life travel forever. I don't know whether it's the British or the Australians - whoever it is, you can kind of stagger into some sort of far-off bastion in the middle of nowhere, and you'll find someone from Britain or someone from Australia or maybe an American.

I absolutely adore and idolise women. All women. I think they are all amazing. The female musicians I've met have been far more inspiring than the male ones. Women tend to be much more creative and ambitious. I think I may have been a woman in a past life.

It's amazing, it's pumping, it's furious, it's anxious, it's happy and it's far more real than anything you'll ever experience in a Western city. Morocco is a living, pulsating entity which is rapidly changing all the time but there are parts of Marrakesh that carry on as they have done for a thousands years. The music is a reflection of that, of all times and all religions and of all the natural expectations and conditions of the people who live there.

When you're singing we all phrase each other in the most remarkable ways. I might hit some sort of thing I've never done before - some vocal pattern. Bonzo will pick it up - he'll phrase with me instantly and then Pagey may join in or start some other phrase - it's like a quadrant.

I think I'm prone to panic.

You would find in a lot of Zep stuff that the riff was the juggernaut that careered through and I worked the lyrics around this.

To rock isn't necessarily to cavort.
