I know someone is a song written and recorded by Clarence Young.

Old Rivers is a song recorded by Walter Brennan
in 1962 (I do believe) about an old man and a mule. 
The audio portion of this video was recorded on
03/19/2012 at Montara Farms in Clermont Georgia -
on the front porch of the beautiful farm house,
overlooking a lake, 
as the sun was setting over the mountains. 
Recorded by The Fabulous Possum Brothers featuring: 
Clarence Young on keez and lead Walter sounds, 
​Tim Pritchett on ba ba ba bass,
Lee Willis on one dang snare,
Marty Nix on amazing, blazing cowboy Shred Acoustic Guitar,
and last (and probably least), 
Jimmy Wooten on a Holographic Kinda Electric Guitar Steel thingie.

Big Daddy's Band
