List of Blue Grass Boys members

The Blue Grass Boys were the backing band for bluegrass mandolinist Bill Monroe. Active from 1938 until Monroe's death in 1996, the group are cited as one of the earliest and most influential groups of the bluegrass genre, which takes its name from the band's moniker. Over its 58-year tenure, the Blue Grass Boys included over 150 members, as well as numerous additional stand-in and guest musicians, many of whom have since been inducted into the International Bluegrass Music Hall of Fame and/or Country Music Hall of Fame. At the time of their first recording in 1939, the group's lineup featured guitarist Cleo Davis, fiddler Art Wooten and bassist Walter "Amos" Garren; at the time of their first release in 1940, Monroe was backed by guitarist Clyde Moody, fiddler Tommy Magness and bassist Bill "Cousin Wilbur" Wesbrooks. The final lineup of the band featured guitarist Tom Ewing, banjoist Dana Cupp, fiddlers Robert Bowlin and Clarence "Tater" Tate, and bassist Ernie Sykes. Monroe died on September 9, 1996, at the age of 84.
