Maren Morris first began to find her now-famous voice as a child, singing at her parents' hair salon in Arlington, Texas. She made her name playing bars across the state before moving to Nashville, where she wrote songs for artists like Tim McGraw and Kelly Clarkson. In 2016, though, Morris recorded one of those songs herself, a love letter to country music called My Church, that became a top-10 hit, won a Grammy, and launched her career. Since then, she has become one of the biggest stars in country music and beyond. In this week's Sunday Sitdown, Maren and Willie Geist got together at a Texas barbecue spot in New York.
