That's not just any cute kid singing the Hank Williams Jr. classic 'Jambalaya.' That's Hunter Hayes, singing with Bocephus over 15 years ago. Four-year-old Hayes found a way to get on stage with Williams Jr., and as you'd expect, he stole the show -- at least for one song.

Not only is Hayes adorable and spot-on with the lyrics in this video, but his accordion playing and stage presence are professional grade. Be sure to watch up to the second solo, when Williams looks to go back to the chorus but Hayes has plans of his own. He gets down like he's been struck by Cajun fever. After the show, we hear the two singers discussed the performance over a meal of crawdads and juice boxes.
