Radio. Michael Bartlett soared to new heights and popularity as a radio favorite. He had his own nation-wide radio program from October 1933 to August 1934. He replaced tenor Frank Parker as a temporary singer on the Jack Benny Hour in 1935—had a 13 week contract.  His singing Through the Years and Ah!  Sweet Mystery of Life on one of the Benny Shows brought an avalanche of fan mail. He left the Benny Show on October 27, 1935, when he signed a long-term contract with Columbia Pictures. On April 16, 1936, through the magic of radio, millions of South Americans listened to a Hollywood musical show that featured Bartlett, Bing Crosby, Francis Lederer, Dixie Dunbar, and Walt Disney’s Mickey Mouse character.  Leo Carillo was the master of ceremonies.  Bartlett appeared on all the major radio programs, including Mary Pickford’s Pickfair, Hollywood Hotel, Lux Radio Theater, Paul Whiteman Hour, Whiteman’s Music Hall, Great Moments in Music, Your Hit Parade, and the Bell Telephone Hour.  In 1940 and 1941, he appeared opposite Marion Claire on the Chicago Theater of the Air in the Chocolate Soldier, Blossom Time, and Bittersweet.
