The Louie Louie/Futurama Link

I just read in a wikipedia article that the Futurama theme song was originally going to be "Psyche Rock" by Pierre Henry, but they couldn't get the rights to the song, so Christopher Tyng composed a song for the show that was very similar. I found a remix of Psyche Rock on the iTunes music store. I also found it and it's derivative remixes listed on a page on the website "The Louie Louie" pages. It was listed in a section with other songs that are not Louie Louie but maybe sort of sound like it. It's 1 a.m., what in god's name am I writing about. Sleeeeeppppp......
