Broadway veteran Bill Carmichael Walsh headlines performances of the 18th annual Broadway Direct show. New and returning stars — from actors fresh off the New York City stage to local high school performers — belt out favorites from My Fair Lady, Fiddler on the Roof, Hadestown, Chicago and Parade. Other highlights include Kathryn Markey’s fan-favorite “Mrs. Santa Claus” routine and a few Beatles and Carole King tunes. It’s all accompanied by the indomitable Scott Nicholas on piano.
