Allen Case grew up in Dallas, Texas, and attended Southern Methodist University for two years. After performing for several months on a local TV variety program, he moved to New York and successfully tried out for a singing spot on Arthur Godfrey's morning show. This led to several nightclub engagements and parts in two Broadway-bound musicals, "Reuben Reuben" and "Pleasure Dome", both of which closed out of town. More work followed in nightclubs and on Broadway, as well as an occasional return to the Arthur Godfrey show and an appearance on Jack Paar. A small part in the movie version of Damn Yankees (1958) meant a move to California which led to roles on such TV westerns as Bronco (1958), La grande caravane (1957), Gunsmoke (1955), Have Gun - Will Travel (1957), L'homme à la carabine (1958) and Sugarfoot (1957). Then it was back to New York for the off-Broadway production of "Once Upon a Mattress". Case left that job to co-star with Henry Fonda in the TV series, The Deputy (1959), which ran for two years (76 episodes) on NBC. Though it made no use of his singing ability, this western represented the high point in Allen Case's career.
