The working relationship was never a problem, you know. We always worked together reasonably well, you know, we always argue, and we always have and always will. I've always argued with Kate, and she's always argued with me, but I guess that's just the way it is, you know, so I feel I'm emotionally involved with it all, to a great extent, you know, much more so than most people would imagine. Not only did we have a personal relationship, and I work with her - I really love her music, I really do... to the point, where I virtually work with nobody else - because nobody else comes close.
