The triumphant return of Sister Act most definitely raised its voice at the opening night at The Dominion Theatre. The movie Sister Act written by Joseph Howard; flows seamlessly from screen to stage; this is beautifully done by Cheri and Bill Steinkellner, with music by Alan Menken and lyrics by Glen Slater. They all honour the original source material, keeping the original film’s message of love and sisterhood at the heart of it.
