Question: I distinctly remember seeing the whole, uncut Biggs, Luke and Red Leader scene, where Red Leader says he met Luke's father. Not in theaters or anything like that, but on TV, around when the SE came out. Entertainment Tonight or something like that. Am I imagining things?
As for the "I saw Luke miss!" crowd, just remember that the music has nothing in it that would fit that event, nor the time for it to happen.
