Chris Willman Senior Music Writer and Chief Music Critic Morgan Wallen and Post Malone have been teasing a joint single, and the two singers premiered the new song, “I Had Some Help,” in a duet performance during Wallen’s headlining set at the Stagecoach festival in California Sunday night. The new song, “I Had Some Help,” is a drinking-buddies anthem and includes the key lyrics “I had some help / It ain’t like I can make this kind of mess all by myself / Don’t act like you ain’t help me pull that bottle off the shelf / Been deep in every weekend, if you couldn’t tell / They say teamwork makes the dream work / Hell, I had some help.” No official announcements have been made about the single, much less a release date.
