Puggo - I have seen Star Wars first time in the 80's on a very very very very high generation VHS with I think polish voiceover. I have seen the VHS tape many, many times during my childhood before I lost (or taped over) it. The Biggs scene was for me always an integral part of the movie. After I went to the cinema to see the '97 SE I found out which scenes were altered / added to the SE. I was surprised to find the Biggs scene on the list, because for me the scene was always the part of the movie. I thought that they actually EDITED it for the SE, because what I remembered was LONGER. It's only after I downloaded the EditDroid bootleg that I realised that this scene was NOT in the "official theatrical version".
I also remember a short "handshaking" scene between Luke and "Wedge" at the rebel hangar briefing room after the part where Luke admits he used to shoot "wamprats" (?) .
When I came here a few years ago, everybody claimed that's just mixed memories, but the only thing I read was the novel, I never read the comic book, and I heard the radio drama just once, and it was only a few years ago
