Back in 1978, Willie Nelson and Waylon Jennings recorded Ed Bruce’s song “Mammas Don’t Let Your Babies Grow Up to Be Cowboys” for their duets album Waylon & Willie. Now over 40 years later, their sons unite to record their own version.
The song was first recorded for the Netflix original show called The Ranch. The show first aired on April 1st 2016 but, a full-length version wasn’t available until now. Nelson and Jennings’ rendition will serves as the centerpiece to a new soundtrack to The Ranch, out Friday.
