2019's CMA Fest earlier this summer was filled with many surprise guests and collaborations, including one by Tim McGraw and Luke Combs.
Ahead of the CMA Fest special premiering on ABC on Sunday night, the Country Music Association has shared a clip of Tim and Luke singing a duet version of one of Tim's smash hits, "Real Good Man."
Luke is a natural on the rocking country track, holding his own with his rugged voice alongside Tim before the two unite on the famous line, "I may be a real bad boy/But baby I'm a real good man."
You can watch the clip right now on Billboard.com, and see the full performance on Sunday night.
CMA Fest will feature sets by country's biggest acts, who performed at Nissan Stadium during the annual Nashville festival. Lil Nas X and Billy Ray Cyrus joined forces with Keith Urban for "Old Town Road," while Carrie Underwood performed a medley of hits with Rock and Roll Hall of Famer Joan Jett.
These collaborations and more will be a part of the special when it airs on Sunday at 8 p.m. ET on ABC.
