The thing is, there is plenty from 1977 for us to pour over and nothing indicates any other cut of the film.
So…in other words, your mom never mentioned it?
??? Your comment makes no sense and is irrelevant. Seems you latched onto one data point and don’t know what to do with it.
I have my own memories of the original (the wider run, not sure if my theater showed the mono mix or stereo mix - though I’m pretty sure the theater was mono). Not to mention all the research I’ve been doing on the sound mixes and their origins. Star Wars was a pretty big deal. It was the first film widely released with Dolby Stereo (a matrixed 4 channel surround format compatible with simple stereo and mono speaker setups). So the original presentation is pretty well documented. And if there had been any alternate cut distributed anywhere, there would be a lot of people with memory of it and knowledge of it. Instead what we find is that those who saw the 70 mm in the early showings have vivid memories of the surround sound and the LFE with no comments on extra scenes. Same with the wider 35 mm release later in 1977. I have come across zero credible reports that any edits were made to the body of the film (the end credits were changed from the first run prints to the wider release prints and Episode IV: A New Hope was added to the crawl and the opening show was recomposited in 1981) between the first showing and the 1997 Special Edition. The few isolated memories, such as mine of Luke making a failed attempt at throwing the grappling hook before a successful second attempt, all seem to stem from creative memories and other sources. I had the script (The Art of Star Wars) and the novel and a few trading cards as well as some other story books. The way movies were distributed pretty much precludes multiple versions going out without someone knowing about it. The first known viewing of the full Toche Station scenes was in 1998 with the Behind the Magic CDROM. The Jabba scene has never been released in its entirety. Plenty of pictures existed and the scenes were in the novel, the published script, and and the Marvel comics. Plenty of opportunity for false memories to be registered, such as mine of the grappling hook, which was never filmed with a first try miss. Memory is a funny thing and it can easily fool us.
