I have been sitting watching that ever since I came back, the continuous variations of light and shadow.
I have definitely written a happy song about someone and then we ended up splitting up, but you have to put those kind of things to the back of your mind and tell yourself that it's a good song and it works on the album.
I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.
