I recently attended The St. Louis Black Rep’s production of Hold On! with Sisters Nancy Corcoran, Barbara Moore and Joan Filla. Hold On! is a play written by Paul Webb that depicts Dr. Martin Luther King Jr.’s historic voting rights marches in Alabama from Selma to Montgomery in 1965 and inspired the 2014 feature film, “Selma.” I knew the play would be moving and that Sister Barbara Moore had been to Selma and marched with Dr. King.
