His name is Keaton, and his grandmother says that not only is he a huge music lover - but that he prefers music over television any day. She recently posted this video on social media of young Keaton covering his idol HARDY's song "Sold Out" - replicating the singer's signature thick-rimmed glasses and all. (Includes colorful language.)

HARDY is currently one of the opening acts for his good friend Morgan Wallen's "One Night at a Time" tour, along with ERNEST and Bailey Zimmerman. Keaton wasn't able to go to Night 1 of the tour's two-day stop in Detroit, but his video made its way to HARDY backstage. Here's a sneak peek of the singer's reaction to Keaton's video.

HARDY got a kick out of Keaton's performance and recorded this special message for the little man, encouraging him to "keep singing and keep throwing that microphone".

That giggle, though.

HARDY first came to prominence in Nashville as a songwriter, penning hits for acts including Florida Georgia Line and Chris Lane - but his breakthrough happened when Blake Shelton recorded and released the song "God's Country". HARDY has emerged as a vocal talent in his his own right, with the chart-toppers "One Beer" and "Wait in the Truck" (with Lainey Wilson) to his credit among others.
