The Band's official alumni organization, the Columbia University Band Alumni Association, registered protests with the administration, and an ad hoc group of alumni writing under the name "A. Hamiltonius" published a series of pamphlets addressing their dissatisfaction with the ban, but at the end of the spring 2017 semester the university administration held firm, prompting the Marching Band to again stage its show outside the building. For Orgo Night December 2017, Band members quietly infiltrated the library with their musical instruments during the evening and popped up at midnight to perform the show inside despite the ban. Prior to the spring 2018 exam period, the administration warned the group's leaders against a repeat and restated the injunction, warning of sanctions; the Band again staged its Orgo Night show in front of the library.
