Which other lines have you recognized as alternate takes in the SW/ANH mono mix? The ones I picked up on myself were both Luke dialogue: “Come on, let’s go have a look. Well, come on!” and “What good’ll it do us if he gets himself killed?”

The only difference I’ve read of in the 70mm mix of Jedi is that for some reason, the crawl music from ESB was tracked in; I have no idea how the edit would have sounded, since the theme leads directly into the next scene. (This info comes from Michael Matessino, who also detailed that the 70mm mix of Empire was near identical long before we found the theater recording, when the speculation about the alternate SE dialogue from ESB/ROTJ being in the 70mm mixes was still being thrown around in fan circles as if it were fact.)
