 When she missed several performances due to illness, Hicks played the role – possibly the only case in the history of the musical where a husband succeeded to his wife's role.After the failure of "Captain Kidd" (1910), Hicks and Terriss concentrated on comedy roles and music hall tours, including a tour of South Africa in 1911 and later a tour of France following the outbreak of World War I, to give concerts to British troops at the front.Their unsuccessful return to musical comedy, "Cash on Delivery" (1917), confirmed the wisdom of their new career course.
