Roth was out of the limelight from the late 1930s. Roth's personal and spiritual feelings led her to convert to Catholicism in 1948. Friends accused her of forsaking Judaism; however, in her autobiography Roth explains that although her parents had believed in God, her sister and she had not been brought up religiously. Roth in her book also insists that she was so inherently Jewish that she could not really forget her heritage and thought that she was "the richer" because of it. In February 1953, she appeared on a special episode of the TV series "This Is Your Life" hosted by Ralph Edwards. In response to her honesty in relating her story of alcoholism, she received more than 40,000 letters. Her theme song, which she began singing as a child performer, was "When the Red, Red Robin (Comes Bob, Bob, Bobbin' Along)".
