The Osbourne Brothers
The Osborne Brothers, Sonny Osborne (b. October 29, 1937) and Bobby Osborne (b. December 9, 1931), were an influential and popular bluegrass act during the 1960s and 1970s. They are probably best known for their No. 33 1968 country hit song, "Rocky Top", written by Felice and Boudleaux Bryant and named after a fictional Tennessee location.
The Osborne Brothers have the distinction of having recorded two songs that would go on to be officially voted as "state songs." The first, "Rocky Top," was named a Tennessee state song in 1982. The other, "Kentucky," was named a state song for the brothers' home state of Kentucky.
In 1994, The Osborne Brothers were inducted into the International Bluegrass Music Association's Hall of Honor. The induction is considered bluegrass music's highest honor.
