I think some drinks were had last night.
While performing at his bar for CRS, Luke Bryan called out to Morgan Wallen who was watching the show side-stage:
“Can you do a full song with a dip in?”
Morgan answered the call, and the two sang Morgan’s hit, “Up Down.”
Side note: I once accidentally swallowed a dip after being paralyzed by its power and yacked with the power of a fire hose.
