Acting is a sport - especially working with Mark Rylance. There is competition involved. I have to be muscular, challenging, get audiences on side. It's extraordinary how Globe audiences join in - it's like competing at an event - I love it.

If you're in pop music, you've got to deal with the changing of the guard every few years. By the time the '70s arrived, I was well aware of the cyclical nature of the game. Pop music is a creature of the moment; it thrives on the mood of its time. Either you hook into that or you're not going to be part of it.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?

It's fun and super exciting to see how other people work, how other people write music, and how other people put things together. To me, it's an endless learning process, and I love doing it because everybody works so completely differently.
