Despite the title, there are no ghosts in The Haunted Hillbilly (currently on at SummerWorks); however, there are plenty of hillbillies, along with a three-piece band, dazzling outfits, bits of stage magic, a rhinestone-studded prosthetic leg, and at least one paraplegic vampire.  Montreal’s Sidemart Theatrical Grocery may have gone a bit over the top in their adaptation of Derek McCormack’s novel, but boy howdy, they had themselves a rootin’ tootin’ good time doing it.
