The original song by the Bee Gees is in a major key and very up-sounding, and I knew it wouldn't fit that way. So I slipped it all into a minor key, so it's the same melody but sadder. We finished the demo and my engineer thought it was one of the best things we've ever done -- and that was just the demo. So I'm pretty good friends with Robert Smith from the Cure who were a big influence on me. We're not just rock buddies, we sort of have a loving relationship from afar. So I called Robert up and said, "Will you sing on my record?" He said, "Sure, whatever you want." I said, "It's a Bee Gees song." Over the Transatlantic line I hear Robert Smith going "The Bee Gees?" I said, "Trust me, just do your thing and it will be fine." He did and it was great.
