On Jan. 2, 1962, The Weavers, a folk music quartet, were banned from appearing on “The Jack Paar Show” by NBC, after the performers each refused to sign a political loyalty oath. One of the most significant popular-music groups of the postwar era, The Weavers career was nearly destroyed during the Red Scare of the 1950s, when Pete Seeger and Lee Hays were denounced as Communist Party members by an FBI informant (who later recanted). The entire group was placed under FBI surveillance and not allowed to perform on radio or television until the late 1950s. In 1955, both Hays and Seeger were called to testify before the House Committee on Un-American Activities, where Hays took the Fifth Amendment, while Seeger refused to answer on First Amendment grounds – the first person to do so after the Hollywood Ten were convicted in 1950. Seeger was found guilty of contempt and placed under restrictions by the court pending appeal, but in 1961 his conviction was overturned on constitutional grounds. Seeger, who left the group in 1958, didn’t appear on television again until 1968 on the Smothers Brothers show.
