Yes people around here like myself are interested to hear how people reacted back then. It's a cliche but it's extremely rare for these type of recordings to come forward.
Here is a thread which lists other Theater Recordings and links to their threads:http://originaltrilogy.com/forum/topic.cfm/Theater-Performance-Preservations/post/454292/#TopicPost454292
I'll add this thread to the list. Feel free to create a name to identify this version. Other SW77 in theater recordings are morgands1, blitter, Belbecus, L.Mayer & BrianM. Only one of these (L.Mayer) has significant 'crowd interaction', most of the recordings were done in empty theaters as the recorders were looking for a clean copy to appreciate the audio mix.
On thing to identify in the recording is which audio soundtrack it was. The Starkiller Mono Mix guide has explanation and audio clips:
To help determine which theater the recording came from, if it is 70mm, this website has a list of all the locations the 70mm screened and when.
Mr. Coate's also identified the ESB 70mm screenings:
Thanks for the info!
