Bluegrass Great Sonny Osborne has died of a stroke at the age of 83. I grew up listening quite often to the sounds of The Osborne Brothers and the great Bill Monroe- my father was a big fan of both artists. I still have some of my father’s old records. Here is The Osborne Brother’s most famous song ‘Rocky Top.’ Sonny is the one introducing the song- his brother Bobby does the singing- Sonny playing the banjo.
