Operas and rock concerts have had live broadcasts often before. The live telecast of a musical performance is a novum. Today Rodgers and Hammerstein's classic musical The Sound of Music will come to the screen in a new live television adaptation starring Carrie Underwood, Stephen Moyer, Audra McDonald, Laura Benanti and Christian Borle. The three-hour event airs live at 8 pm Eastern time on NBC. The telecast is based on the original 1959 Broadway production of the show, starring Mary Martin and Theodore Bikel, with a book by Howard Lindsay and Russel Crouse. Six-time Grammy winner Carrie Underwood stars as Maria and “True Blood” star Moyer as Capt. Georg von Trapp with Tony Award winners McDonald (Ragtime, Master Class) as Mother Abbess, Benanti (Gypsy, Women on the Verge) as Elsa Schrader and Borle (Peter and the Starcatcher, "Smash") as Max Dettweiler.
