In 1985 Ben Burtt remixed the OT's soundtrack and added the mono's 3PO tractor beam line in. This was for the VHS. Does anybody have any idea did the new mix have any other changes from the original theatrical versions (the stereo in the case of ANH) and what those might have been?
Also, was any new material recorded for the 85 mix or was it just made of material that was previously in existence?
