"We don't want to sugarcoat it," Ashley told The Boot. "He has no idea that he has an album out. He had no idea when he won a Grammy."

Campbell won a Grammy for Best Country Song in 2015 for "I'm Not Gonna Miss You," which he wrote and recorded about his Alzheimer's Disease when he was still able to work. In the time between recording and receiving the award, Campbell's illness progressed to the point where he wasn't able to recognize the win.

"I handed him the Grammy when I brought it back to him, and he had no idea what it was," wife Kim said. "But he listens to music, nonetheless. So we always play it for him."

The new album is made up of songs the crooner has always loved, but never recorded and released until now, including songs from Bob Dylan, Willie Nelson and Roger Miller.

Campbell revealed the news of his diagnosis in 2011, when his skills began to decline.

"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," Kim Campbell told PEOPLE. "What you're hearing when listening to 'Adios' 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, and put one last amazing collection of songs onto the record store shelves."

The release of the album is somewhat bittersweet for the family, since Campbell can't grasp how it completes the circle of his career.
