April 14 (UPI) -- Country star Glen Campbell will release a final album, Adiós, in June.
The record will serve as a farewell for the 80-year-old singer, who was diagnosed with Alzheimer's disease in 2011.
Adiós includes 12 songs, and will debut June 9, according to a press release from UMe. Campbell recorded the album in Nashville following his diagnosis and subsequent Goodbye tour.
"Glen's abilities to play, sing and remember songs began to rapidly decline after his diagnosis in 2011," the star's wife, Kim Campbell, wrote in the album's liner notes, according to People. "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."
Campbell collaborated with banjo player and longtime friend Carl Jackson on the album. The record also features Willie Nelson, Vince Gill, and Campbell and Kim's three children, Cal, Shannon and Ashley.
"What you're hearing ... is the beautiful and loving culmination of friends and family doing their very best for the man who inspired, raised and entertained them for decades -- giving him the chance to say one last goodbye to his fans," Kim said.
Campbell has not performed or recorded since 2012, and was moved to a care facility in 2014. He documented his farewell tour and struggle with Alzheimer's in the 2014 film Glen Campbell: I'll Be Me.
