Moorcock actually co-wrote Veteran of the Psychic Wars, and has performed onstage with BOC. A great photo can be found at:http://www.blueoystercult.com/Road/guest.html
That's a trip. I dig the link to the photos!
There's also "The Great Sun Jester" which was inspired by Moorcock's "Messiah at The End of Time." It's on the "Mirrors" album.
