Stagecoach Festival headlining set by Luke Combs featured a Garth Brooks encore, alongside appearances by Good Charlotte, Bailey Zimmerman.

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

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.
