Dropkick Murphys have already managed to raise $100,000 to help those affected in Monday's bombings at the Boston Marathon through proceeds from a special edition t-shirt.
The front says "For Boston" with a photo of the skyline. The back has the city's seal, with the note: Quote, "Thank you, to all who purchased this shirt. All proceeds go to the victims and families of the Boston Marathon bombings. Love, Dropkick Murphys."
