I recently came across a backward version of the main Star Wars theme, arranged by Schananigans. Here's a link for those who want to look at it.

Being the quirky human being I am, I took the idea and ran with it. Instead of taking the ENTIRE song and making it backward, I did it measure-by-measure, so that it's even more confusing. When I was done, I decided to dress it up with some Star Wars sounds, so it sounds like Darth Vader and Luke are battling it out while the song plays backward. I kind of made the battle backward as well, because at the beginning Darth Vader says, "I am your father," and THEN there's the battle, kind of at the end.
I hope you enjoy this and are slightly confused because that's the entire point of it.
