Earl Scruggs and the late Lester Flatt are now members of the Nashville Songwriters Hall of Fame.

Flatt & Scruggs teamed as a bluegrass act in the 1940s. They recorded the theme song to "The Beverly Hillbillies" TV show in 1962, and their instrumental "Foggy Mountain Breakdown" was used in the 1967 film "Bonnie and Clyde."

The duo broke up in 1969 amid a dispute over whether they should try incorporating other styles of music, as Scruggs wanted, or stick with tradition. Flatt died in 1979.
