Noël Coward's "Design for Living" at the Ahmanson Theatre, also in Los Angeles. After this, he went on to perform in "Design for Living" with the National Theatre of Great Britain. During this period Tighe worked with a number of well-known actors including Lorne Greene, Maggie Smith, and Michael Landon before signing a contract with Universal Studios. During Tighe's tenure at Paramount, he appeared on NBC's Bonanza in the episode, "The Weary Willies". 1970s and 1980s Emergency! (1970s) Tighe auditioned for a new Jack Webb television series, Emergency! in 1972 and landed the role of firefighter-paramedic Roy DeSoto, alongside Randolph Mantooth as his partner, John Gage. DeSoto and his team would respond to vehicle crashes, medical emergencies, and other rescues in a fire department rescue squad.
