A pair of country music fans who attended the Route 91 Harvest Festival in Las Vegas last year are asking Jason Aldean to finish his ill-fated set that was interrupted when a shooter opened fire on the crowd. "After it happened, all I could think about was Jason Aldean," says Tiffany Thomas, who started a Facebook group called "58 Survivors 1 Last Set." "I kept thinking he was up there, he was on that stage, he was singing for us." Fellow survivor Gina McKin has since teamed up with Thomas to create a 91-page Shutterfly photo book loaded with pics of fans having fun at the event, which they sent to Aldean along with a request that he return to Vegas to play a special show. "It would just be so bonding and so amazing," says McKin. An Aldean rep says his communications team is "excited" to see the book, but no plans have been made for him to return to Vegas at this time.
