Looks like the 'No Shoes Nation' brought all their rowdy friends to the pah-tay Saturday night in Pittsburgh. And some of them woke up in jail.

From our friends at THE BOOT : Kenny Chesney's concert at Heinz Field in Pittsburgh on Saturday (June 22) ended with public brawls, fans being treated for injuries, and a massive effort to clean up all the debris left behind by 50,000 fans. Nearly 75 people were arrested inside and outside the venue for various offenses, including disorderly conduct, public intoxication and aggravated assault. Another 45 fans were taken to medical facilities. 49 people were arrested inside the venue, and another 29 were arrested nearby, and 150 people were treated for various medical needs.

Here's more info from KDKA TV in Pittsburgh.

Rock on, Kenny...
