Luke Bryan is one heck of a hype man. During a radio industry event at his 32 Bridge bar in Nashville, the country superstar invited Morgan Wallen onstage for a duet on Wallen's No. 1 single, "Up Down."

A video from the event shows Bryan welcoming Wallen onstage for the performance. At first, it seems as though Wallen doesn't want to step on the headliner's toes, so speak, but Bryan cedes the mic with a thumbs up to the up-and-comer.

Bryan stuck around onstage during Wallen's performance, though, accompanying the band on guitar, and occasionally offering up some of the lyrics while sharing the microphone with him. Readers can press play above to watch the full performance.

"Up Down," which originally features Florida Georgia Line, was a No. 1 hit for Wallen. The song was co-written by Brad Clawson, CJ Solar and Hardy.

Bryan and Wallen's performance of "Up Down" took place on Wednesday (Feb. 13), during the 2019 Country Radio Seminar. The gathering of country radio programmers, label executives and other members of the country music industry, ran through Friday (Feb. 15).
