Flatt and Scruggs
Lester Flatt, Earl Scruggs and the Foggy Mountain Boys reached bluegrass legend status with the help of Martha White. In 1953, the company hired an unknown band to barnstorm the South, promoting its flour and corn meal. The members became known as the "World's Greatest Flour Peddlers," appearing on the Grand Ole Opry, playing on the Martha White early morning radio show, and hosting the Flatt and Scruggs television program.
Lester Flatt, who had the voice, and Earl Scruggs, known as the fastest banjo picker in the world, performed at Carnegie Hall twice, played the Hollywood Bowl, recorded the theme song for "The Beverly Hillbillies" and appeared on that television show six times.
