For those interested, I have the 5.1 DTS audio for the Star Wars Trilogy SE trailers B, C, and D.

Trailer A was pulled after release dates when the last 2 films changed. Finding the audio for Trailer A even with it's rare status would certainly be more likely than find the actual film that goes with it. I believe it actually isn't any different than Trailer B, video wise, but since I've not seen it I cannot tell you with any certainty if that's the case.

As far as I know, the Trailer A is the one that says "This President's Day ...".
