Dylan with The Plugz?!?

So I was in Athens last night for the warm up Elephant 6 Holiday Surprise train wreck, er uh, show. At least the movie it was all supporting (Major Organ and the Adding Machine) was absolutely fantastic.

Ran into the manager of Ciné and he said he saw footage of The Plugz backing Bob Dylan on the Letterman show promoting Infidels in 1984. Bull-fucking-shit. But here it is. And here. And here.

Anybody know if they did a session with this line up or were The Plugz just hired hands?
