1978 · Behind the Songs
Two outlaws singing advice they never took themselves.

“Mammas Don’t Let Your Babies Grow Up to Be Cowboys” was written by Ed Bruce and his wife Patsy, and Bruce had a modest hit with it in 1976. But the song was waiting for Willie Nelson and Waylon Jennings. Their duet version, released in early 1978 on the album Waylon & Willie, turned a gentle warning into an outlaw anthem and went to No. 1 on the country chart. The joke, which both singers understood perfectly, is that the two men telling mothers to steer their sons away from the cowboy life were the most famous cowboys in music.

The lyric lists the reasons plainly: cowboys are lonely, restless, hard to love and harder to keep. Sung as a duet, though, it sounds less like a warning than a confession between friends — two men who chose the life anyway and would not trade it. The record itself is relaxed and unhurried, with Nelson’s guitar and Jennings’ baritone leaning on each other like old partners on a fence rail. It became one of the defining singles of the outlaw era, proof that the movement could laugh at itself and still mean every word.
