I was very empty after my father passed away. It was an emotional time, as it would be for anyone, but to be in the studio every day was kind of cathartic and healing and it just seemed very natural to continue.

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.

I've tried to eat little shrubs before. We were on an unsupported 20-plus day traverse, following the migration of endangered antelope across the Chang Tang Plateau. We were like, 'Oh, this is what they ate; we should try it.'
