I spend plenty of time in London and it doesn't scare me, but it's a lonely place, even if you've got friends there. My job takes me all around the world, meeting lots of interesting people. But I think if I couldn't get home, if I couldn't get back to what I consider my real life I'd be frightened.
When you're in a rehearsal room, it's like getting into a car and going on a long journey with everyone's stuff in the back. If you keep stopping the car and going, 'Are you sure we want to go?' and think, 'This is really daunting,' you will get frightened, so you just have to keep ploughing through it.
