The bandmembers arrived at Boston's Logan International Airport on Monday night to board a plane to Ireland and decided to perform for fans in Terminal E as they waited for their flight.

The group belted out its hit I'm Shipping up to Boston, but altered the lyrics to "I'm Shipping up to Dublin" in reference to its trip, much to the delight of the crowd.

The Dropkick Murphys arrived in Dublin on Tuesday morning (17Mar15), in time to celebrate the Irish holiday and kick off their Celtic Punk Invasion Tour with two concerts that night.
