The crowd in Washington Square Park had their hopes dashed when Pete Wentz and the Fall Out Boy impromptu concert got nixed by police.

In town to promote their latest CD Folie a Deux, Pete and the boys were going to give an unscheduled performance but were told that without a permit they couldn’t play and officials went as far as to threaten them with arrest.

Wow, New York is a tough gig.  From the photos it looks like the guys made the best of their appearance before a  large group of fans who turned out for the non-event.
