Added 'blitter' 70mm audio recording info. which seems to be what Belbucus worked from. *EDIT* actually it's 35mm and blitter explains more a few posts down /EDIT

Added info link about morgands1 & BrianM 70mm audio recording.

Updated BrianM version to LMayer.

The LMayer version has 'Crowd Interaction'!!!, from the description:

Both are the original Star Wars, one in May of '77 and the other in early '78. Yes, they are both "snuck-in" open air recordings with the real life "Laugh Track"

So the released BrianM is actually LMayer (Washington D.C.), not sure if the other BrianM (San Diego) was ever released.

*EDIT

Reading further:

The good/bad news is that this is the one recorded at a Monday matinee 11 months after Star Wars opened. Soooo, it has almost no crowd noise, which was the goal
