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.

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.

Combs first brought out Zimmerman as they performed their collaboration, “Back Up Plan,” followed by surprise guests Good Charlotte. First, Benji and Joel Madden performed their hit “The Anthem” with Combs, then joined in on their “favorite” one of Combs’ hits, “Where the Wild Things Are.”
