Cerberus was/is owned by Richard Jones, Muse Margaret's ever-lovin' hubby. I think Richard knew David already, but he really may have known him from The Creature, as Margaret was in it. He did quite a few albums back in the day - several Morricone scores, including La Cage Aux Folles, Zulu Dawn by Elmer Bernstein - some stuff from CBS - radio and TV stuff by Bernard Herrmann, etc.
