The presence of the newer fanfare seems to suggest that your version's audio is derived from the same source as the 1982 VHS/Beta releases, which did have the updated logo and fanfare. Since those releases didn't have the tractor beam line, that means yours is probably the original '77 stereo with the exception of the fanfare. (Evidently, the 1130-84 was a different transfer of the '77 stereo, since it had the old fanfare.)

The 1985 remix, AFAIK, had the original fanfare. My old VHS had the 80s Fox logo, but the original fanfare audio, and it had the tractor beam line. This is because the later pan and scan releases used the 1982 VHS/Beta transfer - the one which wasn't time-compressed. (The time-compressed LD/CED version had both the original logo and fanfare.)

I remember thinking that the 1995 Faces VHS release of ANH looked like a revelation compared to my old tape. Even though we now know how flawed those transfers are, it seemed so amazing back then because those of us without laserdisc or the widescreen box set had been watching a transfer that was over a decade old.

Yeah, my guess is that this Japanese LD is basically the 1982 VHS/Beta version but with digital sound encoding. Great find.
