The Wichita Lineman and Gentle on My Mind singer, 80, recorded the album, titled Adios, after he was diagnosed six years ago, with the help of music stars including Willie Nelson and Vince Gill.
The songs that make up the album were recorded shortly after Campbell’s final tour in 2011.
His wife of 34 years, Kim Campbell said: “Glen’s abilities to play, sing and remember songs began to rapidly decline after his diagnosis in 2011.
“A feeling of urgency grew to get him into the studio one last time to capture what magic was left. It was now or never.”

The idea for the album came from an afternoon the couple spent with Carl Jackson, Campbell’s banjo player and the friend who set the couple up on their first date, according to Billboard magazine.
“We reminisced about all of the songs that Glen had always want to record but had never gotten around to,” she recalled.
Describing the process of recording as “heartbreaking at times,” she went on: “Glen was barely able to remember the words that he was singing at times.
“Carl held up sheets of paper with large-print lyrics and fed them to him one line at a time.”
And she said that despite his advancing dementia he was “clearly ecstatic about being in the studio”.
