Halman and Flynn left the D'Oyly Carte organisation in 1951 and moved to America, where they toured, along with Martyn Green, in a series of Gilbert and Sullivan productions presented by S. M. Chartock. Halman's roles on the 1952 tour included Buttercup, Ruth, the Queen of the Fairies, and Katisha. The Flynns then returned to England, where they settled in Penrith, Cumbria in retirement but were involved with amateur operatic societies, principally the Penrith Savoyards from 1959. In 1975, during the D'Oyly Carte Opera Company's centennial season, Halman was invited to participate in the final performance of "Trial by Jury", in which the regular D'Oyly Carte chorus was augmented by fourteen former stars of the company.
