I can imagine looking over and seeing a grin on my granpa's face when a song like this came on in the truck. Even when he couldn't communicate well, memories like this would ... have an effect. He was about as close as you could get to a cowboy. I'm glad he had those times
Love the song. There's a wonderful studio recording of Keep on the Sunny Side on "Songs of the Famous Carter Family" with Flatt & Scruggs and Mother Maybelle Carter.
