To the OP's original suggestion for only a stanza or line, next to hearing Billie Holiday's voice in my head singing,
Pastoral scene of the gallant South
The bulging eyes and the twisted mouth
the line I personally have the most visceral lyric-vocal reaction to is:
But I shot a man in Reno just to watch him die
When I hear that whistle blowin', I hang my head and cry.
Johnny Cash was the man. And to finish with Hurt? Just amazing.
