Glen Campbell Has Alzheimer's

Country legend Glen Campbell has been diagnosed with Alzheimer's disease and plans to say farewell to his fans with a final tour this fall. The 75-year-old singer and his wife Kim decided to go public with the diagnosis because they want fans who attend the concerts to be aware of his condition. "Glen is still an awesome guitar player and singer," Kim tells People. "But if he flubs a lyric or gets confused on stage, I wouldn’t want people to think, 'What's the matter with him? Is he drunk?' "

Campbell, whose music career stretches over five decades, says the album due out this August, Ghost on the Canvas, will be his last. "I still love making music," he says. "And I still love performing for my fans. I'd like to thank them for sticking with me through thick and thin." (More Glen Campbell stories.)
