April 14, 2021 Sketch of the Day: Mary Livingstone 1905-1983 (The Jack Benny Radio Show) Mary Livingstone was an American radio comedian and actress. She was the wife and radio partner of comedian Jack Benny. Enlisted casually to perform on her husband's program, she proved a talented comedian. But she also proved one of the rare performers to experience severe stage fright years after her career was established, so much so that she retired from show business completely, after two decades in the public eye, almost three decades before her death and at the height of her husband and partner's fame.
