Lester Flatt

Lester Raymond Flatt (June 19, 1914 – May 11, 1979) was an American bluegrass guitarist and mandolinist, best known for his collaboration with banjo picker Earl Scruggs in The Foggy Mountain Boys (popularly known as "Flatt and Scruggs").
Flatt's career spanned multiple decades, breaking out as a member of Bill Monroe's band during the 1940s and including multiple solo and collaboration works exclusive of Scruggs. He first reached a mainstream audience through his performance on "The Ballad of Jed Clampett", the theme for the network television hit The Beverly Hillbillies, in the early 1960s.
