Yesterday I was playing Beethovens fifth, because I love that.

All your travelling is together, you eat together, you're on stage as a band together, when you get to the sound-check the band and the crew are all together.

I've always written in a free, unencumbered way.

I am not in love / But I'm open to persuasion.

You find what you are best at and stick to it. I found my sound early on. Look at U2: they haven't changed their music for 20 years. Anyway, many people come unstuck when they try to change what they do and what they are known for.

So if you're on tour for eight months, a year... or whatever it is you definitely don't want arguments and I'm happy to say that I've always had a really nice bunch of people around me all the time.

That is one of the things about going on tour, that I get to work with some really talented people and it allows me to be able to listen to them as well - and just have fun on stage.
