David Allan Coe has some really good covers.
I can't post the name of one on here, but it's a cover of a song originally by Chinga Chavin, on Chavin's "Country Porn" album. David Allan Coe covered it on track 3 of Nothing Sacred. It's one of the most well executed country songs ever.
"Now, when she took my Cadillac, that didn't bother me a bit, when she took that blue tick hound, she shoulda never done that ****."
He did a cover of the John Prine and Steve Goodman song "You Never Even Called me By My Name" . Which was a complete parody of a country song they wrote one night with a lot of alcohol in a dressing room. Somehow it worked out quite well for him! One of my favorite DAC songs.
