You may have seen this floating around the internet, but this is Luke Bryan in his high school production of Annie Get Your Gun!
Just to set this up for you - Luke plays Frank Butler, a womanizing sharp shooter who comes to town to challenge anyone in a shooting contest. Enter Annie Oakley!
He's actually really good singing Bad Bad Man!
Now if this whole country music thing doesn't work out, I say that he and Reba take Annie Get Your Gun on the road!
