Here’s a great clip of Don Reno and Bill Harrell and The Tennessee Cut-Ups playing on Arthur Smith’s TV show “Carolina Calling”. The clip shows 1971 in the corner but I believe it to actually be around 1974-1975 due to their appearance (clothes and age) and Ed Ferris playing the bass with them.
Don Reno – Banjo
Bill Harrell – guitar
Buck Ryan – fiddle
Ed Ferris – bass
