...then you might like to know that archive.org has "The Star Wars Holiday Special" (1978):

https://archive.org/details/TheStarWarsHolidaySpecial1978

In case it's new to you, this was a bizarre TV variety show featuring the original cast including Harrison Ford, Carrie Fisher, Mark Hamill etc in action/comedy/cartoon/musical skits, but mainly starring other people who had nothing to do with Star Wars.

It was shown once, and never repeated or released in any format.
