Mine's an MR-1.

I received the tape today. Cheap cassette brand, but the sound is remarkably good. I think it's the 70mm mix. I've made it through the first 30 minutes, and it's the "other" Beru. The theater must have had a very nice sound system, as both the highs and the lows sound very clear and full. I'll continue working on it tonight.

The only significant audience reaction so far was when R2 was in the canyon and started acting scared. Lots of clearly audible giggles. I'm sure there will be more to report as I continue to make my way through it.
