Band Aid Columbia's distinctive marching band has a uniform look this season: blue crew-neck sweaters emblazoned with "C," purchased with the proceeds from the band's crash appearance on the Late Show with David Letterman last year. The band showed off its new look Oct. 21 at Wien Stadium at Homecoming, where the iconoclastic players weathered a drenching that only whet their sense of play. Lloyd Allen CC'98, who's called prime minister, at far right in bow tie, and, to his right, John O'Neill CC'97, drum major, flourishing the plunger-baton, lead the band to new complexities. New band member, trumpeter Irene Hecht, at right, marches in her wheelchair. Known for its unorthodoxy, the band has included accomplished players of the mailbox, plumbing-pipe didgeridoo, pasta package and kitchen sink.
