The Hullabahoos are a student-run, all-male a cappella group at the University of Virginia in Charlottesville. The group was founded in 1987 by Halsted Sullivan and continues to be one of the premier men's groups in the country, having recorded 15 studio albums as of early 2007 and performed for thousands of people at such venues as the 2004 Republican National Convention, Washington Nationals baseball games, Good Morning America, the Philippines, weddings, and private parties. Other performance requests have included invitations from the White House, the Kennedy Center, and NBC's The Today Show.
