Students protested a taping of the "Hootenanny" television show on April 15, 1963 at Rutgers University in New Brunswick, New Jersey. The protest was due to folk singer Pete Seeger not being invited to participate in the show due to his political beliefs and concerns, which effectively blacklisted him from network television. About four hundred "singing, card carrying students" protested outside of the Ledge, while inside there was an audience of approximately six hundred students.
