The appearence of this song on Nashville Skyline is notable, as it is a duet between Mr. Dylan and the Man in Black himself, Johnny Cash.

Dylan and Cash split the verses pretty evenly, and sing together on the "chorus", which is the repition of the first verse. Their voices blend well together despite their "rough" sound, with Dylan handling the higher registers and Cash using his distinctive voice to lend a hand on the lower.

In addition the song is given a slower, more plaintive feel and the addition of a lead guitar adds complexity to the sad tale of distant love.
