Chuck Berry does Zep?

A club that's known not only for booking good oldie acts but also for booking cover bands evidently mixed up the two for this ad. You have to admit though, it would be kind of interesting to hear Chuck cover Zep. Anyone going to the show shouldn't expect that of course- after all, CB doesn't need to cover anyone else's songs since he's got such an amazing batch himself. Maybe Robert Plant will return to Zep to cover Chuck's song though...
