This is an all-time fave of mine. I first heard it a "Jesus Drinks Free", a vinyl night run by Boston Hassle in Jamaica Plain where the DJs would play country western, soul and gospel tracks at the Jeanie Johnston Pub. This song stuck in my head, there is something that really hit me with the refrain "So you think you're a cowboy/but you're only a kid".
Also, I've said it before and I'll say it again, Emmylou Harris has a GOAT voice.
