I contacted them recently to see if they have any plans to screen this again for the 30th anniversary and i was told that they had got into a lot of trouble showing this version and it was recalled immediately after. When our old main cinema was closed down and demolished they found a copy of the print in the vaults which they shouldn't have had. So it looks like lucasfilm really doesn't want the original ever to be shown again.
That's the third example I've heard of. Fucking LFL.
