Vinyl LP pressing. To commemorate the final season of The Ranch, Netflix has partnered with Curb Records for the release of The Ranch ( A Netflix Original Series Official Soundtrack ). Among the soundtrack's many highlights is the series' acclaimed theme song, "Mammas Don't Let Your Babies Grow Up To Be Cowboys," a rendition of the Ed Bruce country classic performed by Lukas Nelson and Grammy Award winner Shooter Jennings. This special Lukas/Shooter duet was recorded specifically for The Ranch and has never been released. It comes more than 40 years after their fathers-country music icons Willie Nelson and Waylon Jennings-recorded their cover of the song, which hit #1 on the country music charts and won a Grammy.
