^He’s saying that the version heard in the film isn’t on the soundtracks, and I can’t confirm that he’s correct, but it’s definitely not anything that hasn’t happened before. Same with Gonna Fly in Rocky, the (superior, IMO) version from the film isn’t included in the soundtrack, being replaced with a different recording.
EDIT: You beat me to the punch SplikaBilka. I guess I typed too much.😃
