Glen Campbell's wife says Alzheimer's disease has robbed the 80-year-old singer's ability to play guitar.
But Kim Campbell told The Tennessean that her husband occasionally breaks into a solo air guitar routine, which she says is "kind of fun."
Glen Campbell was diagnosed with the brain-ravaging disease in 2011 and went on a world tour afterward. The singer known for such hits as "Rhinestone Cowboy," ''Wichita Lineman" and "Southern Nights" was moved to a long-term care facility in 2014.

Kim Campbell says he continues to sing, although the words are gibberish and "it's not a melody that we recognize, but you can tell that it's a happy song and he has a song in his heart," so that brings her great comfort.
In an interview in April, Kim Campbell said, "Faith has always been the central part of our relationship. I’m so pleased that as Glen has entered the later stages of this illness, it’s evident that he has retained his awareness of God. That really comforts me to know that he has that sense of God’s presence in his life, that he’s not alone."
