ROGER: You know that Star Wars is just a hit I had years ago turned up-side down? That's right. Anybody remember "Born Free"? We had a big hit on that. Well, Star Wars is just "Born Free" up-side down. I don't think you believe me. Mike, did you dig up that music? I wanna show you. Now this is the music to Star Wars. I'm gonna play it for you, then I'm gonna turn it up-side down and play it for you, and you'll see it's "Born Free". Okay? Here is Star Wars. [He plays the excerpts transcribed below.]
There are undeniable similarities, but, is Roger Williams actually correct in his assertion? If we take his rendition of the Star Wars main theme and turn it upside down (i.e. rotate it 180 degrees), here's what you get: click here to listen.

But, of course, there are similarities. After all, Roger Williams' track wouldn't be funny if a listener could discern no such correlation. Those similarities, though, are not the product of inversion, but rather identical rhythms. However, he had to alter the rhythms of the Star Wars theme in order for that to be the case. Here's the theme as Roger Williams played it, with the original rhythm below:
Thus, Roger Williams' comment that Star Wars is "Born Free" up-side down is not accurate in the least. He makes this point in jest only.
