The Man in Black was indeed in an earlier cut of my list but I thought I'd leave the door open for somebody.
I always thought that this song was from the late 60s but I guess that's just me associating it with the At Folsom Prison live album.
This is definitely country - I think that rockabilly crosses over between country and Rock and Roll and is therefore fair game for this week. Great choice. Listening to this highlights the difference between "original country" (for want of a better term) and "The Nashville Sound".
