Born in 1936 in Arkansas, Glen Campbell moved to Albuquerque, N.M., at 18 years old to join his uncle's band. After two years playing with his uncle and in his own band, the Western Wranglers, the future musical icon moved to Los Angeles in 1960 to be a studio musician; his guitar skills earned him spots on records from artists such as Bobby Darin, Nat King Cole, Merle Haggard, Elvis Presley and the Monkees, among others. Campbell's own first album as an artist, 'Big Bluegrass Special', was released in 1962; however, it wasn't until 1967's 'Gentle on My Mind' that he earned his first No. 1 record. The legend released more than 30 albums on Capitol Records -- projects that spawned No. 1 hits such as "Wichita Lineman," "Galveston" and "Try a Little Kindness," among others -- before moving to Atlantic Records and a series of other labels beginning in the early 1980s. Campbell also found success as a TV and movie star, in films such as 'True Grit' and 'Norwood' and as the host of TV shows such as 'The Glen Campbell Goodtime Hour' and 'The Glen Campbell Music Show'. In 2011, Campbell revealed that he had been diagnosed with Alzheimer's disease and embarked on a farewell tour that ended in November of 2012. His final performances, as well as his battle with the illness, are documented in the critically acclaimed documentary 'Glen Campbell ... I'll Be Me'. Married four times, Campbell has eight children.
