My local neighborhood put out a FaceBook invite for a movie night next week, announcing it as "the original Star Wars." When I inquired about whether the original version of one of the Special Editions would be played, I was answered with "Original," with a smiley emoticon.
Inferring based on the perceived enthusiasm, I'd say it will be legitimate. No idea whether it will be film-based, or Harmy's Despecialized Edition, or what. Given the very small scale of the event, probably the latter. Either way, it ought to be great fun and a rare chance to see it in a public manner.
