I've actually had a couple of PMs asking me for my recording in spite of the fact it's most likely the 35mm mix. I went ahead and uploaded them to rapidshare for anyone interested:

Again, the recording is in pretty bad shape, don't expect much. If anything it's a good reference as far as content goes-- straight from the film projector.
