Tracking his father's battle with the disease, Sonny Louvin wrote on Charlie's Web site last summer: "The surgery did not go as planned. He will begin using alternative methods of treatment, going forward."
An active musician since the '40s, best remembered for his for his work with brother Ira, Alabama-born Charlie Louvin also released 19 solo albums. Among the hits, according to The Tennessean: "When I Stop Dreaming," "I Don’t Believe You've Met My Baby" and "My Baby's Gone" – songs that influenced Emmylou Harris, Alison Krauss and Dolly Parton.
In 2001, Louvin was inducted into the Country Music Hall of Fame for his body of work with brother Ira (they broke up the act in 1963, and Ira, who battled alcohol and other demons, died two years later, at age 41). In 2008, Charlie released two albums, Ships to Heaven and Sings Murder Ballads and Disaster Songs.
Last month, according to The Tennessean, Louvin made his last onstage appearances, and is quoted as saying: "In my world, you are worthless if you can't continue. Show business is all I really know how to do. I would like for that to be the last thing I do."
