Country legend Glen Campbell, best known for the 1975 hit "Rhinestone Cowboy," has died at age 81.
TMZ reports he died around 10 a.m. Tuesday in a Nashville facility for Alzheimer's patients. His farewell studio album, Adios, was released earlier this year. The country legend released more than 70 albums over his half century in the music industry. He sold 45 million records, netting multiple Grammys and other awards over his career.
Campbell was diagnosed with Alzheimer's in June 2011. He kicked off on a "Goodbye Tour" a short time later, and checked into a long-term care facility in 2014.
Campbell is survived by his wife and eight children.
