Sister Act: The Musical A CADOS Production Music by Alan Menken Lyrics by Glenn Slater Book by Cheri Steinkellner & Bill Steinkellner Additional Book Material by Douglas Carter Beane Based on the Touchstone Pictures Motion Picture, Sister Act, written by Joseph Howard. Directed by Zoe Jones A divine musical comedy based on the hit film When disco diva Deloris Van Cartier witnesses a murder, she is put in protective custody in one place the 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 uptight Mother Superior. 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 is giving chase only to find them up against Deloris and the power of her newly found sisterhood. Featuring original music by winner Alan Menken ( Disneys Aladdin, Enchanted ) and songs inspired by Motown, soul and disco, this heavenly musical is joyous and uplifting in equal measures.
