Producer Whoopi Goldberg joined the sisters of the Tony Award-nominated Broadway musical at Macy's. The cast, decked out in Chanukah-colored habits, performed "Raise Your Voice," the musical's first-act finale.

The Sister Act cast stars Olivier Award nominee Patina Miller as Deloris Van Cartier, Tony Award nominee Carolee Carmello (Parade, Lestat) as Mother Superior, Fred Applegate (Young Frankenstein) as Monsignor, Sarah Bolt (Wicked) as Sister Mary Patrick, John Treacy Egan (The Producers) as Joey, Demond Green (The Toxic Avenger) as TJ, Chester Gregory (Dreamgirls) as Eddie, Kingsley Leggs (The Color Purple) as Curtis, Marla Mindelle (South Pacific) as Sister Mary Robert, Audrie Neenan (Picnic) as Sister Mary Lazarus and Caesar Samayoa (The Pee-wee Herman Show) as Pablo.

According to producers, “When disco diva Deloris Van Cartier witnesses a murder, she is put in protective custody in the one place cops are sure she won’t be found – a convent! Disguised as a nun, she finds herself at odds with both the rigid lifestyle and an uptight Mother Superior (Victoria Clark). Using her unique disco moves and singing talent to inspire the choir, Deloris breathes new life into the church and community, but in doing so blows her cover. Soon the gang are giving chase, only to find themselves up against Deloris and the power of her new found Sister Hood.”
