I've heard at least part of that disco remix several times several years ago, but I've never seen that video before in my life, until today of course :P . The simplified C-3P0 and Darth Vader costumes...they almost seemed like the costumes that would have been used if Star Wars was a tokusatsu production...

...that reminds me. Someone should make either a toku or anime(esque) adaption of the namco star wars famicom (japanese nes) game, with Luke flying the Millenium Falcon in search of certain members of the rebel alliance and fighting off dozens of Darth Vader doppelgangers that turn into monsters with his lightsaber. Of course, since the famicom version of TESB is the same as the US version but in japanese, it needs not be adapted. Think of the possibilities though...
