Rogers wrote some score (maybe a dozen cues); there was a resource online I can't re-locate now that had paper work information and it included cue titles for the film, done by Rogers. I don't know if he recorded anything.
Walton/Khatchaturian/Arnold hated the film and turned it down.
Jarre said that he viewed 40 hours of footage from the movie. I wonder how much of that footage still exists. It was an extraordinary accomplishment to compose and record that score in just 6 weeks.
