Grammy-winning singer Glen Campbell reportedly has been moved to a care facility, three years after he was diagnosed with Alzheimer's disease. A family friend told PEOPLE that the "Rhinestone Cowboy" singer was moved to the facility last week, adding, "I'm not sure what the permanent plan is for him yet. We'll know more next week."
Campbell opened up about the diagnosis in an interview in 2011 when he was planning goodbye concerts for fans. "Glen is still an awesome guitar player and singer. 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?' " his wife Kim Woolen said of revealing his condition back then.
The legendary musician's smashing hit "Rhinestone Cowboy" topped the charts in 1975. He won four Grammy awards in 1976 and was inducted into the Country Music Hall of Fame in 2005. Campbell, who is popular for songs such as "Gentle on My Mind" and "By the Time I Get to Phoenix", sold 45 million copies of albums during his career.
"I still love making music," Campbell added in the interview. "And I still love performing for my fans. I'd like to thank them for sticking with me through thick and thin."
