For me it’s more that I remember the distinct impression that something had changed the first time I saw it in general release in 1978. I remember at that time questioning whether I really remembered Luke missing the previous 6 or 7 times I saw the movie (first run)? Of course at that time I was under the impression that movies were carved in stone and never changed once they were released. As I previously described I don’t believe there was any difference in the length of the scene. A change in the length would require alteration to the music. I simply believe that 141 frames that may have originally shown Luke missing in the 35 first run 35mm prints, were replaced with a different 141 frames that don’t show Luke missing in all other prints. No change in time or music.
