42nd StreetSharon Playhouse in Sharon, Conn.Book by Michael Stewart and Mark BrambleLyrics by Al DubinMusic by Harry WarrenDirected by Carl Andress“Are the stars out tonight? What makes the Warner Brothers film “42nd Street” so wonderful is its nominal star, Ruby Keeler. Her talent is her dancing, a street form of tap dancing that is both awkward and amazing. What’s wrong with the Sharon Playhouse stage edition of this project is its nominal star, Gabi Stapula. “42nd Street” continues at the Sharon Playhouse, 49 Amenia Road, Sharon, CT, through August 9.
