NY1 VIDEO: On this week's On Stage, hosted by Frank DiLella, we trace the history of 6-time Tony Award-winning musical "Dear Evan Hansen." The episode features Frank's interviews with cast members Ben Platt and Rachel Bay Jones, composers Benj Pasek and Justin Paul, book writer Steven Levenson, director Michael Greif, and orchestrator Alex Lacamoire, dating back from the show's original out-of-town run in 2015, all the way through Tony night.
