Adiós, Glen Campbell

I already covered this once, here:

The great musician was 81, and we knew he was suffering from Alzheimer's disease. From the obituary in Variety:

Born into a sharecropping family in a tiny town in southwestern Arkansas, Campbell was the seventh of 12 children. Picking up guitar at an early age, he left home at age 14 to pursue music... Out west, Campbell soon found himself an in-demand session musician... recording guitar parts for such varied acts as Nat “King” Cole, Frank Sinatra, the Monkees, Merle Haggard and Elvis Presley.
Campbell reached the height of his session player power in 1965, when he became a touring member of the Beach Boys — playing bass to compensate for the absent Brian Wilson — as well as contributing guitar parts to the group’s landmark “Pet Sounds” album...
... Campbell’s career experienced a sudden, dramatic upswing in 1967, when he recorded a rendition of John Hartford’s “Gentle on My Mind.”... Follow-up single “By the Time I Get to Phoenix” was an even bigger hit.... [H]e began hosting a weekly CBS variety show, “The Glen Campbell Goodtime Hour”....
