Well, The Spin told you that Wanda Jackson's still got it, and if you missed the show at TMR Tuesday night, and then you missed her appearance on Letterman last night when it was broadcast on the TV, here is some AV for you. Check out those moves! The band's crackin', too. Speaking of the band, somehow the camera manages to cut to the back-up singers at the exact moment when they get out of sync and bump into each other. (You may recognize one of those back-up singers as Ashley Monroe, who appeared on the cover of the Scene last February.) Anyway, fun performance — and enough to make David Letterman say "holy crap."
