I heard the US Navy's bluegrass band Country Current perform at IBMA a few weeks ago. They performed a song about two people named Tom and Katie Harper. I don't remember much about it other than them living together in a cabin on the hill he built in the fall of "67".

I'm in the process of contacting the band, but I recall it being a nice song, so figured I'd ask here to see if anyone else knows it, and will share here if I get an answer.
