The context in which Darth Dan posted seemed to me to mean it was cut from one version and seen in another. That sceen and the, I believe, Toshi Station scene are routinely believed to have been in a released version. Growing up I had "seen" them in things such as books and radio dramas and the effect is that you believe you saw them in a movie, which they never were. There was a CDROM - Star Wars Behind the Magic or the supplemental material included with Yoda Stories which was the first time the material was actually released. I'd have to check my CDs to make sure which one it is on. Anyway, I believe they were also shown at some Comic Con or similar prior to that. I also remember reading a Sansweet article on the topic, probably in one of my old Star Wars Insider magazines.
Good God, yes. It was originally released some 30 years ago. I got to listen to it during the initial run as well as ESB but I didn't even know whether or not the did a RotJ until I pick
this up. Star Wars in particular is excellent as it expounds greatly in some areas most notably some background between Leia and Vader as well as Alderaan. The set looks pricey now but I consider it a must own. Actually, I looked up my order from seven years ago and it is less now. I purchased the Dark Forces audio drama based on the three [somewhat] graphic novels at the same time. I do not consider that a must own.
