Everybody has seen the humorous Elvis impersonators who mimic his karate moves. This old footage of the real Elvis shows that many of the imitators were not far off. I'm not much of an Elvis fan, however, I will not openly speculate on whether I think Elvis was a "good martial artist" or not. At this point, who really cares? The fact is, he really did seem to have a passion for MA.
Regardless of any of that, I find this footage interesting, as it shows a snapshot of karate in the U.S. during the early '70s. IMO, the most interesting parts feature Bill 'Superfoot' Wallace, who at the time was one of Elvis' trainers. Here, Wallace demonstrates more of a classical karate approach, as opposed to later, when he went into "full-contact karate", a.k.a., kickboxing.
I've always been dubious of the manner of many of the demos, particularly the Kenpo style of a dozen hits on an attacker who steps in with a punch and stands frozen like a mannequin.
Elvis looks a bit drunk to me. His dojo attire in interesting, "because he's Elvis."
