Oh, what a beautiful morning! Nobody sang that at the 2010 Broadway on Broadway concert, but they could have, since September 13 turned out to be a picture-perfect day to enjoy performances by Broadway’s brightest stars in the middle of Times Square. It was a smashing kickoff for the fall season, as cast members from current and upcoming shows took the stage to perform musical numbers for adoring fans. Heck, even the mayor came to enjoy the festivities! Take a look at Broadway.com’s complete coverage of this fabulous event.
