Interesting - is there anything about the Criterion's track that sets it apart from the standard Columbia release?
In any event, a decent preservation of the theatrical stereo would be very welcome. I note that there was also a 70mm 6-track mix back in the day, though I'm having a hard time finding any details - it was likely one of those cases where the actual content of the mix differs little from the stereo. If anyone knows any better please chime in...
