Songwriting is about getting the demon out of me. It's like being possessed. You try to go to sleep, but the song won't let you. So you have to get up and make it into something, and then you're allowed to sleep. It's always in the middle of the bloody night, or when you're half awake or tired, when your critical faculties are switched off. So letting go is what the whole game is.
