Hilariously Awful Donny and Marie Osmond STAR WARS Parody

So here's something that I've never seen until today. It's a retro 1970's video of a Donnie and Marie Osmond Star Wars parody. Did Star Wars fans enjoy this kind of stuff back in the day? I was embarrassed for everyone involved with this as I watched it. Good lord... what were they thinking!? The show also features Redd Foxx as Obi-Wan Kenobi and Kris Kristofferson as Han Solo. It's always interesting coming across stuff like this. 

The question I have for you is... is this better or worse than the prequel trilogy?
