Harris continued as the Chorus's conductor until 1936; he was succeeded as Music Director/Conductor by Léon Barzin (1936-37), Willard Sektberg (1937-42), Hugh Ross (1942-195?),
In 1965, when David Buttolph resigned, the Chorus recalled how much they had enjoyed making music with David Randolph when he had substituted at a rehearsal in October 1959, and invited him to become their sixth Music Director/Conductor.
