Rinzler's Making of ESB discusses this on page 333 'A Twist Ending' section. One of the shots they extended and added dialog to was of the farewell at the end. A shot of the Falcon docked under the cruiser was not in the 70mm. Anyone know of any others?

This is a possibilty, early prints verses prints made as popularity grew. The two opening day thing is definitely a complication in the 'original' debate.

So at this point it's throwing out ideas of ways to figure out why these differences occurred and thinking about other locations they might have showed up. Was thinking are there any books from 1977-81 in which the credits might have been written out. Maybe a press book, art book or the original novel? Were the screen plays printed out then? Another idea to follow through on, anyone know where 16mm prints were generally created from back then? Did they tend to be source from 70 or 35mm? Need to float the question to a larger audience see what comes back.
