Days before the Columbia University Marching Band prepared to take the field for the Lions’ football home opener against Georgetown on Saturday afternoon, band leadership was informed by Athletics Director Peter Pilling, Associate Athletics Director Bob Steitz, and Director of Student Engagement William Lucas that the group would not be allowed to perform at upcoming athletic events. The group, which has been in existence since 1904 and battled the university administration for years, “will no longer exist in any official capacity,” it announced in an official statement Wednesday.
