I was there.
1. From what I've read, it was actually the 1981 re-release print, as it had "EPISODE IV - A NEW HOPE" and "Close the blast doors! Close the blast doors!" was missing.
"Close the blast doors" was missing in the first 1977 run as well - it didn't appear until the mono mix, which was finished some time after the Dolby mixes.
The 1981 print you saw probably had the original 1977 Dolby Stereo sound mix.
