"Yodelin' Slim Clark" hailed from Maine, and performed for 70 years. Yodeler Don Walser was from Texas. Though he was widely known in Texas, his singing career did not really take off until he was 60 years old in 1994. In 2000 he received a lifetime "Heritage" award from the National Endowment for the Arts, and he and his band played at the Kennedy Center for the Performing Arts. Jimmie Davis, who served two terms as the Governor of Louisiana, was also a successful country singer who yodeled.
