I Don't Need No Doctor -- you like?

The latest and greatest cover of “I Don’t Need No Doctor” (readily available on le iTunes on a computer near you!) is performed by Scofield. And, um, John Mayer. I’m somewhat ashamed to admit that I’ve been grooving along happily all the afternoon.

Am I an irredeemable philistine, or are any other Dopers belting out, “He gave me a medicated lotion/but it didn’t soothe my emotion”?
