From another thread:
There is that 1999 DVD release of Alien (1979) that has the production audio in one of the audio tracks, but the audio is not complete, as that track also has a few alternate music score cues. That feature has not been carried over to the 2003 DVD release nor the blu ray release.
Can somebody please sync this to the regraded Blu-ray and post it to the spleen? Also, are there any other bonus audio tracks like this for Alien or Aliens?
