That's off his latest album and is a remake of one of his earlier songs. A few weeks ago, I pulled out the original (recorded in 1957 -- yeah, 45 years ago) and listened to it back-to-back with the remake. You could really hear a difference in the....I don't quite know the word...perhaps "soul" is the most appropriate.... Anyway, you could really hear the difference in the "soul" of that song that four and a half decades lend to Johnny Cash's interpretation of it.
I wonder how many people can record a song, have it be a hit (I think it made it to #13 on the country chart -- not too shabby), then wait 45 years, record the same song again, and have it win a Grammy.
I really dig Johnny Cash. Check out my (horribly outdated) tribute pages.
