LITTLE ROCK, Ark. (KTHV) -- The trombone is a unique instrument, and one herd of cows is a big, big fan.
Farmer Derek Klingenberg posted a video to his YouTube of him playing Lorde's "Royals" on the trombone to an empty field, then slowly you see cows coming over the horizon right to him.
You can see them crowd around him and even join in at one point!
