Tim McGraw and Luke Combs stormed the Nissan Stadium stage with a boot-stomping rendition of McGraw's "Real Good Man" on Saturday night (June 8.) The fun went down during McGraw's 2019 CMA Fest set at the stadium, when he brought Combs -- who had also performed earlier in the evening -- back to the stage for a surprise duet. Press play above to watch!

The pair traded off verses on "Real Good Man," keeping energy levels high throughout the duet and closing the song with an enthusiastic hug. In his own set earlier in the night, Combs brought the same rock 'n' roll vibes as he powered through his biggest hits and closed with his latest release, "Beer Never Broke My Heart."

McGraw originally released "Real Good Man" as a single in 2003, where it topped out at No. 1 on the charts. The song is included on his 2002 album, Tim McGraw and the Dancehall Doctors. Neither of the two country artists is a stranger to the top spot on the charts, with Combs boasting a five-song string of consecutive No. 1s off his debut album, Here's to You.

The ace duet came as a showstopper to an already incredible lineup at Nissan Stadium on Saturday night. Miranda Lambert debuted a new song during her set that evening. Dierks Bentley brought tourmate Tenille Townes to the stage during his performance. Billy Ray Cyrus took an entire stadium of concertgoers down to "Old Town Road" when he not only brought out rapper Lil Nas X to perform their hit collaboration, but also invited Keith Urban to the stage to add a banjo to the mix.
