Kacey Musgraves' sold-out four-night run at Nashville's Ryman Auditorium has included a surprise guest at each performance: On Wednesday night (Feb. 27) it was Paramore's Hayley Williams; on Thursday night (Feb. 28), it was CeeLo Green; and on Friday night (March 1), it was none other than Brooks & Dunn. The iconic country duo joined Musgraves onstage to perform their song "Neon Moon."

Readers can press play above to watch Musgraves, Kix Brooks and Ronnie Dunn sing "Neon Moon," a 1992 single from Brooks & Dunn. The duo's third overall single together, the song was written by Dunn and became a No. 1 hit.

Musgraves began covering "Neon Moon" solo during shows in early 2018. She'll team up with Brooks & Dunn for a re-imagined studio version of the track on the pair's upcoming Reboot album. Due out on April 5, the project features Brooks & Dunn re-recording some of their most famous tracks with some of today's biggest country names: In addition to Musgraves, the project will also feature Kane BrownThomas RhettBrett YoungLancoAshley McBrydeMidlandLuke CombsBrothers OsborneCody Johnson, Jon Pardi and Tyler Booth.

Musgraves' four nights at the Ryman conclude on Saturday (March 2). The shows are part of her Oh, What a World Tour, in support of her Grammy Awards-winning third studio album, Golden Hour.

Both Musgraves and Brooks & Dunn have something else exciting to look forward to this year: They will be the subjects of exhibits at the Country Music Hall of Fame and Museum. Musgraves' exhibit will open in July, while Brooks & Dunn's will open in August. Other artists being honored with Hall of Fame exhibits in 2019 include Keith Whitley and songwriters Boudleaux and Felice Bryant.
