If you've ever felt the uncontrollable urge to burst into song while watching your favorite musicals, then this sing-along to The Sound of Music is for you. This evening at Hollywood Bowl begins with your host leading you through a vocal warm-up. Then, you'll get a primer on appropriate heckles and accompanying actions to use during the movie, such as hissing at the countess, barking at Rolf and, of course, cheering for Maria. With the song lyrics on the screen, you won't miss a chance to sing your heart out. Costumes are not compulsory, but they're highly recommended, and you'll be amazed at the inventiveness on display. Get swept away by the romance, touching family story and heartbreaking drama of the musical story of Maria and the Von Trapp family, as you belt out out such classics as "My Favorite Things," "Do-Re-Mi," "Climb Ev'ry Mountain," "Edelweiss" and, of course, the enchanting title track.
