First time I heard this was when Blake Shelton covered it for his Pure BS album. Really loved the song. Then I found the original and enjoyed it too (though Blake's take is very true to the original, I sorta like it better just because I heard it first). I think the sentiment of the song is really interesting and real. Anyways, cool to see that the song is on someone else's list of favorites too.
I also like this song, though being a John Anderson fan, I especially like his version from a 2001 album called "Nobody's Got It All."
Everything Chris Knight does is pure gold.
