I can't leave the studio until everything is as it should be. And I can't put a record out unless I am completely happy with it. I never want to be at a signing and hear my album playing and think, 'Oh no, I could have done that top note better.'
And I find - I'm 63, and my capacity to be by myself and just spend time by myself hasn't diminished any. That's the necessary part of being a writer, you better like being alone.
