Listen to Karen O. sing "Mamas Don't Let Your Babies Grow Up to be Cowboys" for Chipotle.
Yeah Yeah Yeahs singer Karen O. recorded this rendition of "Mamas Don't Let Your Babies Grow Up to be Cowboys," the duet Willie Nelson and Waylon Jennings made famous in 1978. Karen sang it for the Chipotle Cultivation Foundation, which supports initiatives of sustainable agriculture, including U.S. family farms. David Atobelli directed this short film set to Karen O.'s haunting version. If it doesn't make you really sad, you've probably never played tag in a haymow.
