Covered Up: Generally averted since Keith writes about 95% of his material, but it's happened a couple times:
"A Little Less Talk and a Lot More Action" was originally recorded by Hank Williams, Jr..
He covered Sting's "I'm So Happy I Can't Stop Crying" as a duet with the original artist. The duet outpeaked Sting's original on the pop charts.
A strange zig-zagging came with "I Can't Take You Anywhere". Keith originally recorded the song, but co-writer Scotty Emerick released it as a single two years later. Emerick's version featured a guest vocal from Keith.
Tear Jerker: "Cryin' for Me (Wayman's Song)", a sincere tribute to basketball player/jazz musician Wayman Tisdale.
