I posted a recreation of the 70mm ending of ESB in one of the threads around here a few months ago, just for fun to see and hear how it actually played, you can check it out here: http://www.sendspace.com/file/6nt4ow
Just a quick and dirty edit and sync job of the 70mm audio and GOUT. I actually think it worked better in some ways, the pace, no tracked music... the establishing shot of the fleet which ends on the Falcon became somewhat awkward in the reedit IMO. Both versions works in their own way of course.
Edit: here's a good thread for the various 70mm differences in ESB: http://originaltrilogy.com/forum/topic.cfm/70-mm-print-of-the-Empire-Strikes-Back-Differences/topic/2321/
