"Man of Constant Sorrow" (also known as "I Am a Man of Constant Sorrow") is a traditional American folk song first recorded by Dick Burnett, a partially blind fiddler from Kentucky. The song was originally recorded by Burnett as "Farewell Song" printed in a Richard Burnett songbook, about 1913.
An early version was recorded by Emry Arthur in 1928 (Vocalion Vo 5208). It became popular again when it was played in the 2000 movie O Brother, Where Art Thou?.
