A Minnesota dinner theatre lands the rights to produce the world premiere of “Easter Parade,” a stage version of the classic 1948 movie with music by Irving Berlin. “Though new musicals frequently begin life outside New York, it’s unusual for a theater — particularly a dinner theater in the suburbs — to earn the right to develop a high-profile title on its own. The Chanhassen production, scheduled to open in February, will be the template for amateur and professional productions. It could have a life on the road and has an outside shot at advancing to Broadway.”
