Country music star Lee Ann Womack has been singing along to “Three Days” since she was a little girl raiding the record collection of her dad, who disc jockeyed at a small country radio station in East Texas. It’s a deep cut off Willie’s 1962 debut album, and it prompts thoughts from Lee Ann on the unexpected places where songwriters find the lines to write old-school country songs, the difference between Texas country music and the rest of it, and the lessons that she and her two daughters—who are also both singer-songwriters—learned from going on tour with Willie.
