I'm blessed as my father loved Bluegrass & Country and my mother loved what she called 'Boogie Woogie' and so I appreciate all kinds of music.
Just watching this video was a joy and at the same time a heartbreak.
While I may have missed some, I know that the following who were in that video are no longer with us. All were great performers and caring human beings.
Earl Scruggs
Chet Atkins
Jimmie Martin
Johnny Cash
Roy Acuff
Vassar Clements
