The leading lights of ‘70s outlaw country came together as a twosome for this 1978 album, crafting the musical equivalent of a classic Western buddy movie. As the duo delivers tongue-in-cheek anti-anthems like “Mammas Don’t Let Your Babies Grow Up to Be Cowboys” or Kris Kristofferson’s “Don’t Cuss the Fiddle”, you can picture Willie and Waylon riding down the dusty old road together, leaving a trail of broken hearts and empty whisky bottles behind them.
