Well, I have to say that the in theater audio recordings pretty much rule out there being an early, different cut. The one I’m thinking of in particular was an early 70 mm showing and it is pretty well documented that there were only 2 versions of the film in 77 and they only differ by audio and the end credits. Anything else anyone claims to remember is a false memory that came from some other source besides the film. You may not even remember which of the many sources for these other scenes it was. My memory of Luke missing his first try with the grappling hook came from the novel. Biggs showed up in books and trading cards And don’t know where all. An active imagination coupled with these other sources pretty much explains any unverifiable memory of a scene. You can claim you remember it all you want, but that doesn’t make it true. The new scans of several 35 mm prints as well as 16 mm prints and the oldest video recordings all agree on the cut of the film and no evidence has ever come to light that there was ever another cut. From my understanding, the Toshe Station scenes were never included in any cut because they were the first thing cut and were only filmed because they were the first scenes ready to shoot. Lucas had written them at other people’s suggestion and didn’t like how they turned out. Jabba was cut because it was never supposed to be human and they ran out of time to do any effects. When you research the available material on these extra scenes, it is clear they were cut early in editing so it is impossible to have seen them until they were released years later. But photos were out in 77 as was the script. The novel was out 6 months before the film. The other sources of those parts of the story coupled with the nature of human memory makes a false memory more than likely.
