Wayne Cochran and the C.C. Riders on The Jackie Gleason Show, sometime in the late 60s. Words fail me.
The thing is, as ridiculous as the idea of a Caucasian James Brown might seem in the abstract, Cochran actually was kind of the real deal. He wrote "Last Kiss," too, which means he deserves respect from mere mortals like you and me and Eddie Vedder.
Apparently he's found Jeebus in his old age, which of course isn't all that big of a shock.
