The Osborne Brothers

The Osborne Brothers, Sonny (October 29, 1937 – October 24, 2021) and Bobby (December 7, 1931 – June 27, 2023), were an influential and popular bluegrass act during the 1960s and 1970s and until Sonny retired in 2005. They are probably best known for their No. 33 1967 country hit song, "Rocky Top", written by Felice and Boudleaux Bryant and named after a Tennessee location.
