Not sure what Twyla Tharp has to do with Smokey Joe. She's not listed in either the Broadway production or my local one. Maybe she directed the Raleigh version a few years ago?
My program says: "Originally produced on Broadway by Richard Frankel, Thomas Viertel, Steven Baruch, Jujamcyn Theaters/Jack Viertel, Rick Steiner, Frederic H. Mayerson, and Center Theatre GRoup/AhmansonTheatre/Gordon Davidson."
Our director was
Robert Barry Fleming. He's a professional director and head of the theater department at the University of San Diego.
Aside from all this, the Sampson Theater version is not tied to the Broadway choreography; as Fleming explained to us, licensees are only bound to use the song list in the same order, though the song may be adjusted for the singer's gender. The set, the singers and the dancing are all up to the local director.
