Yes, the show was shut down during the last song, "Radicals", by the Boston police.
Jasper was inebriated, and it was rumored that he fought a cop, leading to the shut down (this is only speculation). At one point in the show, Jasper threatened to jump from the balcony, forcing the members on stage to stop mid-song and ask the fans to stop him from doing so.
There was no opening act. Instead, a 20 minute preview of the group's new show "Loiter Squad" was played.
