The reigning queen of country music, Miranda Lambert, talks about one of the all-time great Outlaw anthems, Willie and Waylon’s Grammy-winning, #1 hit from 1978, “Mammas Don’t Let Your Babies Grow up to Be Cowboys.” It’s a song Miranda can’t remember ever not knowing, one she suspects she first heard her dad played on the front porch, before she could even walk. The memory of those family get-togethers gets her thinking about the vital role pickin’ parties have played not just in her own life, but in country music history, the first song that ever made her cry, and the debt that every country artist owes to her hero, Willie Nelson.
