Margo Price headlined her first show at Nashville's Ryman Auditorium on Saturday night (May 19), and she pulled out all the stops. Special guests, covers and epic moments were sprinkled throughout the show -- including an appearance from Sturgill Simpson.

Together, Price and Simpson covered Conway Twitty and Loretta Lynn's classic duet "After the Fire Is Gone." Readers can press play above to watch their performance of the track, which originally appeared on Twitty and Lynn's 1971 album We Only Make Believe. It wasn't Price's first time covering the iconic duo, though: Earlier this year, she and Paul Cauthen covered "You're the Reason Our Kids Are Ugly" during a show.

On Saturday night, Simpson also joined Price's opening act, Tyler Childers, onstage for two songs, "Honky Tonk Flame" and "Whitehouse Road." Both songs appear on Childers' 2017 debut release, Purgatory, which Simpson co-produced (with David Ferguson) and on which he plays guitar and sings backup.

Simpson wasn't Price's only special guest of the night: Lukas Nelson joined her for her song "Learning to Lose," which appears on her sophomore record, All American Made. The studio version of the song features Nelson's father, Willie Nelson.

Price's Saturday night Ryman setlist also included a cover of Dolly Parton’s classic “9 to 5." Price headlined the iconic venue on Sunday night (May 20) as well, and has one more show scheduled there, on Wednesday (May 23).
