An a capella rendition by the Persuasions.

Pretty fucking cool, if you ask me.

Per Wikipedia, Zappa funded the Persuasions' first LP. One more thing I love about Frank: he loved good music in all genres, and was generous with his money when it came to helping talented artists. (Could be bullshit, of course, given that it (1) is Wikipedia and (2) has a "[citation needed]" next to it, but even if this story's apocryphal, we know he helped guys like Alice Cooper get started.)

This is from the album Frankly a Capella, released in 2000 and still available. I'm a big advocate of supporting your local record store, but if you don't have one anymore, well, here's a damn Amazon link.
