Glen Campbell is one of the most exceptional talents in the history of popular music. Beginning with a stellar career as a first-call session musician, Campbell appeared on a slew of hit records in the 1960s by artists as diverse as Simon and Garfunkel and Frank Sinatra. After Brian Wilson quit the Beach Boys, Campbell came in to replace him in the group's live shows before launching his own solo career in the late '60s.

The '70s saw Campbell become one of the most successful singers in the world, with a long string of country hits, a run of sold-out concerts and his own network television show. His records brought together his vocal and guitar talents with some of the world's top songwriters, most notably Jimmy Webb, who penned several of Campbell's most significant songs.

On June 22, 2011, Campbell revealed that he had been diagnosed with Alzheimer's disease. Campbell continued with his plans to embark on a farewell tour and performed his final show on Nov. 30, 2012. On Tuesday (Aug. 8), he died at the age of 81.
