Luke Bryan fans apparently left a huge mess after his show at Heinz Field in Pittsburgh on Saturday night.
Mayor Bill Peduto is calling for concert promoters to take more responsibility when it comes to clean-up and public safety issues caused by the shows.
Safety officials responded to more than 300 incidents related to the show, including breaking up several fights, arrests and medical calls resulting in transportation to hospitals.
Luke tweeted fans, asking them not to leave trash behind. According to officials, the debris left behind at last year's Kenny Chesney show at the ballpark was a lot worse.
Also. I know your guys have heard. Be mindful of your tailgate area. Clean up please. We wanna come back many more times.— Luke Bryan (@LukeBryanOnline) June 20, 2014
The bad behavior of fans at the show inspired this video, which has been making the rounds on social media.
