According to Carrie Fisher, George Lucas gave her a copy of the special as a gift for recording the DVD commentary for Star Wars: Episode IV - A New Hope (1977). She claimed that she played it at parties when she wanted her guests to leave.
George Lucas famously tried (and failed) to buy up all master copies to make sure it was never broadcast again.
Bea Arthur claimed she only appeared in this special because her younger son was a big fan of Star Wars: Episode IV - A New Hope (1977).
The special has never been released on video, but bootleg videos circulated for years, and the show can be seen all over the internet. George Lucas remarked at an Australian convention, "If I had the time and a sledgehammer, I would track down every bootlegged copy of that program and smash it."
