Casey tossed the fan the T-shirt, and the clip ended. See it for yourself below. Dropkick Murphys' next show will take place tomorrow night (March 11) in Wilkes Barre, Pa.

Casey swapped it for a Dropkick Murphy's t-shirt, which he said was "proudly made in America." After the show, Casey told me he approached the fan in the MAGA clothing.
