Gabriel has made the original multi-track tracks available for some of his old 1980's stuff. People are remixing them and adding stuff. If you become a member of Real World Remixed, you can upload your own creation for the group to hear and vote on.
This is Games Without Frontiers with Tony Banks style organ bits.

I wouldn't have the patience / tolerance to listen to Shock The Monkey over and over and over again while remixing it. I've already heard that one enough for this lifetime!
