June Carter Cash
In later years, the Carter Family treated "Keep on the Sunny Side" as a theme song of sorts. A 1964 album by the Carter Family (with special guest vocalist Johnny Cash) was titled "Keep on the Sunny Side", and Cash recorded a version for his 1974 album "The Junkie and the Juicehead Minus Me" accompanied by June Carter Cash, Johnny Cash's daughter Rosanne Cash and June Carter's daughters Carlene Carter and Rosie Nix Adams. June Carter Cash also recorded a version for her final solo album, "Wildwood Flower", released posthumously in 2003.
