Singer-songwriter-superstar Kacey Musgraves goes deep into Willie’s back catalog to discuss “Are You Sure.” It was one of the first demos he cut when he moved to Nashville—though it’s probably best-known by the duet Kacey and Willie recorded for her Grammy-nominated 2015 album Pageant Material—and it prompts her to talk about what she calls “real-ass country songs,” the lucky joint Willie gave her, and singing “Rainbow Connection” with him at the 2019 CMA awards. Oh and she also does the best Owen Wilson impression you will hear all year.
