So Dierks Bentley is freaking out just a little! He found out the other night that U2 covered "Drunk On A Plane" during their concert in Louisiana! Dierks said, " Trying to process… #U2 breaking into drunk on a plane last night. Can’t make this up. #drunkonaplane #beautifulday.” I mean, some of the biggest rock stars in the world, covering Dierks....that is pretty amazing!
