Although Emry Arthur’s version of “Man of Constant Sorrow” sold well, it was not until The Stanley Brothers released their version in 1951 that it really became popular. Their version changes the song into much more of what we know today. Specifically, they turn it into a bluegrass song with that classic howling voice. It also adds a much more lively accompaniment with that relentless fiddle. Ralph Stanley just had his 88th birthday. His brother Carter died back in 1966 at the age of only 41.
