Here's parts 2-3 of the Pastoral. It's kind of a mess. I don't know whether they cut the film further at the spots where the '82 mix drops out, or if that was editing to fit it onto the soundtrack record... Either way, it is not going to be fun. I'm having the same issues with Night on Bald Mountain...
Also, my thoughts on a "Sunflower" scene are this: since they wouldn't have been present in the '82 version, I think I would even have cut it had it been present on the BR.
