IIRC (and I often don't) BOC was supposed to do some music for the film "Heavy Metal" and though the deal fell through ,they released some songs that mention characters in the movie. (Sorry to be so vague but, though I was involved in the film and the soundtrack, I didn't know much about heavy metal music so left that to others. I did meet Bruce Lundvall who was representing Columbia records, so he and I talked about jazz while others dealt with the rock. I remember showing rough cuts of the film to Ronnie Dio and Don Felder but had no idea who they were. )
