A five-year run on Broadway is a serious accomplishment, particularly when the show is still doing sellout business. Such is the case with Jersey Boys, which marked its fifth Broadway birthday on November 7 with a daylong celebration. Broadway.com snagged an invitation to the musical's anniversary party on the enclosed rooftop at the Empire Hotel, where we were honored to speak with original Four Season Frankie Valli as well as the show’s current stars and members of the creative team. Who loves you, Jersey Boys? We do.
