Ottis Dewey Whitman, Jr. (born January 20, 1924), known professionally as Slim Whitman, is an American country music and western music singer/songwriter and instrumentalist known for his yodeling abilities and his smooth high octave falsetto. He has sold in excess of 120 million records. He is consistently more popular throughout Europe, and in particular Britain, than in his native America, particularly with his covers of pop standards and movie songs, love songs, folk tunes and gospel melodic hymns. His 1955 hit single "Rose Marie" held the Guinness World Record for the longest time at number 1 on the UK Singles Chart until Bryan Adams broke the record in 1991 after 36 years. In the U.S., his "Indian Love Call" (1952) and "Secret Love" (1953) reached number 2 on the Billboard country chart. Whitman had a string of hits from the mid-1960s and into the 1970s and became known to a new generation of fans through television direct marketing in the 1980s. Throughout the 1990s and into the 21st century, he has continued to tour extensively around the world and release new material, and he was featured on the soundtrack of the 1996 film Mars Attacks!. In 2010 a new album, called Twilight on the Trail was released.
