Glen Campbell Moved Into Care Facility, Unable to Attend His Documentary Debut

The premiere of Glen Campbell's farewell concert documentary at the Nashville Film Festival on Friday will be a bittersweet affair. The 77-year-old country crooner will not be able to attend the screening because he was recently moved into an Alzheimer's care facility.

The film, "Glen Campbell… I'll Be Me," chronicles the emotional twists and turns of the country singer's diagnosis with Alzheimer's disease two years ago, when he was told by doctors to hang up his guitar. Instead, he and his wife, Kim, publicly announced the diagnosis and embarked on the highly successful Goodbye Tour, which saw Campbell and his family band playing sold-out shows across the country.

During his concerts, the multiple-Grammy-winning performer would occasionally forget the words to his songs or lose his place, but his band would gently remind him. Campbell handled things with grace and humor, joking with the audience, "I forget a lot lately, y'all ever get that?"

In addition to touring, the highly prolific "Rhinestone Cowboy" singer released two albums in the past two years while dealing with the disease — "Ghost on the Canvas" and "See You There."

Now, as the disease progresses, Campbell's family has made the decision to place him under monitored care. "He was moved to an Alzhemier's facility last week," a family friend told People. "I'm not sure what the permanent plan is for him yet. We'll know more next week."

Campbell's legacy include the hits "Galveston," "By the Time I Get to Phoenix," and "Wichita Lineman"— stark reminders of why he's been able to so successfully cross over between the pop and country charts during the span of his impressive 50-year career.
