Country legend Glen Campbell recently told 'People' magazine that he has been diagnosed with Alzheimer's. The 76-year-old Country Music Hall of Famer has a new studio album, 'Ghost On The Canvas' coming out on August 30th and plans to do a farewell tour. Campbell's wife Kim told People, that when he performs on stage and flubs a line or appears out of sync, she doesn't want people asking if he is drunk which is one reason they decided to go public. Campbell began his chart run in 1962 with 'Kentucky Means Paradise' which went top 20. He scored the first of five number one singles in 1968 with 'I Wanna Live' and followed that up with four more number one's that all went gold including 'Wichita Lineman', 'Galveston', 'Rhinestone Cowboy' and 'Southern Nights'. 'Rhinestone Cowboy' is probably his most popular hit that charted in June of 1975. Campbell was born in Delight, Arkansas in 1936 and became a prolific studio musician which included work with the Hondells in 1964, The Beach Boys in 1965 and the Champs. Campbell hosted a populr TV variety show from 1968-1972 on CBS called 'The Glen Campbell Goodtime Hour'. He starred opposite John Wayne in 'True Grit' and has won several CMA Awards over his great career. The 'Ghost On The Canvas' album will be his last and he will retire at the conclusion of his farewell tour. We wish Glen Campbell nothing but the best as he deals with this devestating disease.
