"So it became in my mind a nine-carol service; an oratorio and orchestral concert all in one, but with narration. That's something I've learned about, because it's the story that keeps you in there. I wrote a libretto and I gave it to John Du Prez. We normally don't work in this fashion but I said off you go, and he went off for about three months. He brought me back this demo which blew my mind."
