That’s a good question. According to a few sources, the original Wings trailer (http://www.thx.com/consumer/movies/8492259) was used before Jedi in 1983. That said, though they generally indicate that it was first seen at the Premiere (was it Grauman’s for this one?) they don’t comment on how widespread it was beyond that - indeed, how many THX certified theatres were there in 1983?

So possibly not as much a part of the movie as the Fox fanfare, but still an appealing addition for a certain kind of preservation. I wonder if anyone who saw Jedi in a US theatre during its initial run can comment further?
