“I would like, if I may, to take you on a strange journey.” If you haven’t yet been initiated in to the fellowship of Rocky Horror fans, the Mandela Forum will afford you six raucous occasions to join. The Jim Sharman-Richard O’Brien classic comes to Florence for back-to-back performances in original language, of the original version, first staged at London’s Royal Court Theatre in June 1973. A kitschy show paying homage to corny sci-fi and “scary” flicks, the play begins with a couple caught in a storm, who eventually make their way to the home of mad scientist Dr. Frank N. Furter, a transvestite with a peculiar creation he’s eager to show off. It’s hard to believe, but the show’s first Broadway run closed after just 45 performances, a small price to pay for the cult fame that would come later.
