Ozark Mountain Daredevils and "Jackie Blue"
...
Interesting. I somehow never connected that song with the Daredevils. For me, their big song is Chicken Train--but it never charted like Jackie Blue (1, USA) and "If you wanna get to heaven" (21, USA)
{wife is from their hometown of springfield, and I'm from STL, so we both had little choice but to listen to that band!}
In any event, in my subjective book (worth, perhaps, a plugged nickle), not a one-hit wonder.
