Glen Campbell diagnosed with Alzheimer's

Glen Campbell’s wife Kim has revealed that the country music singer has Alzheimer's disease.

The couple has decided to go public with Glen’s diagnosis because he is hoping to say farewell with a final slate of live performances this fall and they want his fans to be aware of his condition.

“Glen is still an awesome guitar player and singer,” the People magazine quoted Kim as saying.

 “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?” she said.

The grammy-winner, whose Rhinestone Cowboy had topped the charts in 1975, had been suffering from short-term memory loss for years, but the Alzheimer's diagnosis only came six months ago.

“I still love making music. And I still love performing for my fans. I'd like to thank them for sticking with me through thick and thin,” the US country music veteran said.
