The free "Broadway on Broadway" concert, the annual event held in Times Square at the beginning of each Broadway season, has been set for Sunday, September 14. The casts of existing and upcoming Broadway shows will perform in front of approximately 50,000 fans on a stage set up in the heart of Times Square just for the concert. "Broadway on Broadway" begins at 11:30am, but you should arrive a couple hours early if you want to get up close to the stage.
