In 1976, I met Mark Hamill in the STAR WARS ROOM at the Science Fiction World Con in Kansas City. No one had any idea what STAR WARS was, but I remembered Mark from the Texas Wheelers. He signed a poster for me (sold for a lot of money years ago). He was a very nice guy.
I'm pretty sure this is from one of the first 4 episodes during the Autumn 1974 run, especially when it includes different closing titles. Can't remember what the episode's title was.
