Today is Star Wars Day, or "May the 4th be with you." Something less than a national holiday but more than a horrific pun, it's evidence that we still very much live in a Star Wars world 35 years after the movie was released, as well as that once the Internet gets ahold of an idea, the rest of us might as well get on board.
But a long time ago, in a galaxy far, far away, Star Wars was just George Lucas's shoestring-budgeted space opera with a bunch of no-name actors and that one guy who was in The Bridge on the River Kwai. Obviously he went a different way, but it's easy to imagine Lucas auditioning many of music's biggest stars at the moment for the film. He might not have been able to afford them back then, but it's fun to think about.
