Combs keyed up expectations as he told fans something special was on the way to help him close out an already-rousing festival set. Playing somewhat coy, he sang the first portion of "Friends in Low Places," only for Brooks to quietly appear on stage and take over.

The musician took his own turn popping up during another artist's performance when he joined Backstreet Boys for "I Want It That Way" later that night

Luke Combs closed out the night with a headlining set that perfectly captured the festival’s spirit, blending country tradition, heartfelt storytelling, and a few unforgettable surprises along the way for the official finish line of the Stagecoach Country Music Festival on Sunday night.
