PUP, the excellent Canadian punk band (and one of our 40 favorite new bands of the year) had a bit of a surprise for their audience last week at the Halifax Pop Explosion Festival, when they started covering Fucked Up’s “Queen Of Hearts,” from their last album David Comes To Life (our #4 album of 2011). People were excited enough about that, but once Fucked Up frontman Damian Abraham jumped on stage to actually take the lead vocals the crowd went absolutely bonkers. You can watch the video of the performance below.

PUP’s self-titled debut album is available now via Royal Mountain.
