Special Guest is Providence College's only all-male a cappella group. Since its inception in 1996, the group has been performing on the PC campus, around Providence, and around New England for anyone willing to listen. The boys of Special Guest are notorious on Providence's campus for breaking hearts, making knees weak, and being really, really, ridiculously good looking in the black and tan. Their traditional annual performances include Fall, Christmas, and Spring concerts;
