Last weekend, after their show in Barcelona, Spain, the quartet made some new friends in a local bar, who coaxed the rockers to a nearby fiesta, where they performed impromptu versions of "A Punk" and "Cape Cod Kwasa Kwasa," as partiers sang along.
According to Prefix, the show was a present for a girl's birthday party. And the dude on the keyboards subbing in for the absent Rostam Batmanglij is sooo happy this clip made it online. Hello, music career.
