If a drive-in counts as a theatre, then I did indeed see it in the theatre in 1977 (and yes, two standby’s). The “misunderstanding” I’m referring to is that you seem to think you need to be old like me to have seen/heard a theatrical print, or that the Despecialized Editions are somehow limited to home video releases and don’t use theatrical prints. Theatrical prints are still with us (often in bad shape, sure, but they exist), and in many private collections around here. They are used in the Despecialized Editions. You don’t need someone who was even alive in 77 to tell you what was on those prints, you just need someone to walk over to those prints, check it out, and report back*. As I said, it’s settled. There were only two standby’s. Checking with other peoples’ equally faulty 40-year-old memories is not much value to anyone, especially when we are swimming in so much hard evidence that’s so easy to consult.
I’ve linked to the print variation thread in a post above, and a google site search on grappling hook will get you to all kinds of threads about our most common false memories.
EDIT: Oh, in addition to the original film reels, we also have in-theatre audio recording from the time, too. They’re not good enough quality to make a good soundtrack out of them, but they can be used to verify details like this, and… well, you probably know what I’m going to say about them next. Two standby’s.
* Technically, they may not be willing to do it just for this. But seriously, we’ve got lots of different people people poring all over these things on lots of different prints all the time, and maybe you just have to be around here long enough to know that if someone, in all of that time, discovered an even slightly different soundtrack variant (and extra standby’s definitely qualifies), it would have been front page news around here long ago. Take a look at the print variations thread–does it really seem like people who notice that sort of thing and have access to this sort of material wouldn’t have already noticed this?
