Also, member Gregaton mentioned earlier this year: http://originaltrilogy.com/forum/topic.cfm/Hopefully-the-last-70mm-vs-35mm-ESB-audio-differences-thread/post/573758/#TopicPost573758 Yoda's "Ehhhh!" was there at some point before the SE. I have an old VHS tape with a recorded 1980 tv review of the movie, and a clip from that scene shown during the review features the "Ehhhh!"
I wonder if this version is the sound mix that was on those clips sent to TV stations/etc. by Fox/Lucasfilm for promotional purposes. TV was still exclusively in mono, so would it be too much of a stretch that the clips sent out used a mono mix?
(I know I've seen a Siskel and Ebert episode from 1980, around the time ESB came out, which showed clips of the first film with the mono mix.)
