The Statler Brothers (sometimes simply referred to as The Statlers) were an American country music, gospel, and vocal group from Staunton, Virginia. The quartet was formed in 1955 performing locally, and from 1964 to 1972, they sang as opening act and backup singers for Johnny Cash. Originally performing Southern gospel music at local churches, the group billed themselves as The Four Star Quartet, and later The Kingsmen. In 1963, when the song "Louie, Louie" by the garage rock band also called The Kingsmen became famous, the group elected to bill themselves as the Statler Brothers.
