After the D'Oyly Carte Opera Company closed, Sandford continued his association with Gilbert and Sullivan. He acted as managing director of a touring concert group, "The Magic of D'Oyly Carte" (later called "The magic of Gilbert & Sullivan") and along with his friend and former D'Oyly Carte colleague Roberta Morrell, he appeared in and co-directed several Savoy Operas at Gawsworth Hall, Cheshire. Sandford toured North America several times with Geoffrey Shovelton, John Ayldon, Lorraine Daniels and others in a series of Gilbert and Sullivan concerts entitled "The Best of Gilbert & Sullivan", and in other concerts and productions, including at the Berkshire Choral Institute with John Reed in "The Gondoliers" (1985).
