OK. I've posted this on two Stones sites and gotten no response. SO HERE! Mid Seventies an animated film along the lines of Heavy Metal comes out featuring big acts of the day. Typical stuff with lush graphics set to music. Now the only sequence that stands out in my memory was the final sequence of creatures soaring through the clouds all backed up by a killer Rolling Stones song I have never heard elsewhere and am unable to locate. It sounds like Exile On Main Street era stuff and something that would have ended up on a B-side single. No hit potential but damn fine rock. I keep thinking it must be Heavy Metal but there no Stones tracks on there. Unless it was only in the movie.
