Broadway’s illustrious Roundabout Theater Company rolled out the red carpet at the Roseland Ballroom on March 14 when it celebrated its 2011 Spring Gala: Alec Baldwin: A Musical Tribute. Stars of stage, screen and Roundabout shows past and present assembled at the New York landmark to honor—and serenade— the 30 Rock star and Broadway vet. The starry crowd, including Baldwin’s 30 Rock co-stars Jane Krakowski and Cheyenne Jackson, enjoyed cocktails and dinner, a live auction and an original musical tribute to Baldwin, all in the name of benefitting the Musical Theatre Fund of Roundabout Theatre Company.
