Luke Bryan got into the spirit of Las Vegas on his last night there, which also happened to be the day before what would have been the late Elvis Presley's birthday. On stage, Luke payed tribute to the King, channeling his inner Elvis and launching into a more-than-respectable version of Elvis' single, "The Wonder Of You." Posting the clip to Instagram, Luke wrote, "Listened to this over and over as a kid. Fun to do a small clip on my last night in vegas. Happy Birthday Elvis."
