Burton also appeared on Broadway in the musical "Camelot" and the play "Hamlet" directed by John Gielgud. He appeared on television in 1960 as Caliban in the Hallmark Hall of Fame production of "The Tempest" with Claire Bloom and Maurice Evans. He also appeared on "The Ed Sullivan Show" with Julie Andrews to sing "What Do the Simple Folk Do?" from "Camelot". This appearance boosted ticket sales for the stalled musical.
