Since this seems like it might be the best quality source available at the moment for the original Star Wars stereo 35mm soundtrack, has Hairy_Hen used this as the source for his restored/corrected 1977 Star Wars stereo soundtrack?

He's used it as a source for his 70mm mix, but for fairly small sections IIRC (an explosion on Tantive IV... and that may be it). H_H's 70mm project predates this one and I believe switching over to an entirely new source for most of the audio would have created more problems than it solved--keep in mind that while this recording is clearly the current best-of-breed for 1977 stereo, 1) it is not without its problems, and 2) its better dynamic range is not such a standout when compared to later audio revisions, from which h_h based much of his audio.

And yes, I'm also interested in hearing Empire and Jedi!
