I hadn't heard of these until the Despeciaized edition of A New Hope came out. I would be interested in hearing the full commentary, since it was edited to be played with the original version. Does someone have these commentaries? I tried to look them up, but couldn't find anything, because I didn't catch what the commentator's name was.

I'm not sure I quite understand what you're saying here, but you can find some info here:

Come to think of it, I don't recall listening to them myself, mostly because I just can't stand the SEs so taking these discs out isn't a thought I entertain... at all, really. The box itself is nice, though. Really cool cardboard.
