You know what? I forgot that the original was not actually changed until AFTER Empire in 1980. I thought that he had changed it to A New Hope in the 1978 Star Wars re-release. Now you remind me that it was with Empire that we learned about the 9-part series that had started with Episode 4. Thanks for the reminder. And I also remember how big a deal that seemed at the time.
By the way, do you remember when you first saw Star Wars, and what you thought at the time. Were you a kid, with your family, or with friends?
I remember seeing at in our "new" second-run 99-cent theatre, after everyone else had seen it, but still loving it. It popped off the screen, and made a huge impression. I had an LP of the story with some sound effects that I played over and over. I also watched it later when it would come on HBO and things like that.
