That tour and the way he and his family dealt with the sometimes painful progress of his disease were chronicled in a 2014 documentary, “Glen Campbell: I’ll Be Me,” directed by the actor James Keach. Former President Bill Clinton, a fellow Arkansas native, appears in the film and praises Mr. Campbell for having the courage to become a public face of Alzheimer’s.
At the height of his career, Mr. Campbell was one of the biggest names in show business, his appeal based not just on his music but also on his easygoing manner and his apple-cheeked, all-American good looks.
