Ottis Dewey "Slim" Whitman (January 20, 1923 – June 19, 2013), known professionally as Slim Whitman, was an American country music and western music singer, songwriter and instrumentalist known for his yodeling abilities and his smooth, high, three-octave-range falsetto in a style christened as "countrypolitan". He stated that he had sold in excess of 120 million records. In the 1950s Whitman toured with Elvis Presley as the opening act. In the 1990s a new generation was exposed to Whitman through his songs featured in the film Mars Attacks!; his iconic Indian Love Call would kill the invading Martians every time the record was played.
