I'd spent five hours that morning trying to write a song that was meaningful and good, and I finally gave up and lay down. Then, "Nowhere Man" came, words and music, the whole damn thing, as I lay down. . . Song writing 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 sleep.
The grey is certainly inspired by the photo-paintings, and, of course, it's related to the fact that I think grey is an important colour - the ideal colour for indifference, fence-sitting, keeping quiet, despair. In other words, for states of being and situations that affect one, and for which one would like to find a visual expression.
