The most scared I'd ever been was the first time I sang at a rugby match, Australia versus New Zealand, in front of one hundred thousand people. I had a panic attack the night before because people have been booed off and never worked again... just singing one song, the national anthem.

Becoming a father, I think it inevitably changes your perspective of life. I don't get nearly enough sleep. And the simplest things in life are completely satisfying. I find you don't have to do as much, like you don't go on as many outings.

When people stop me in the street, and I can see they want to tell me more than they want the selfie, they want to tell me what it means to them, and that means a lot to me.

At which point should we let go and do what we want to do, and when should we submit to rules? Coming to terms with our true natures and who we really are has always been a fascination to humans. I know it fascinates me.

I have a terrific marriage, but unlike a lot of relationships where they ebb and flow, no matter what happens you fall deeper and deeper in love every day. It's kind of the best thing that can happen to you. It's thrilling.

I hate being frightened of things. I'm not someone who can say: "Oh, I'm scared of flying, I won't fly." Fear seems to creep over every part of your life so if there's something I identify as frightening to me I want to tackle it.

One of things I'd love to do one day is a Shakespeare with Trevor Nunn. I've done musicals with him, but never Shakespeare. There's no one better.
