Judy Collins sings Russian on Rainbow Quest

Back in the mid-sixties Pete Seeger had an educational TV show called Rainbow Quest. In 1962 the Court of Appeals had ruled that the House Un-American Activities Committee was faulty in its charges against Seeger and dismissed the case against him. With his newfound freedom, Pete was anxious to appear on TV again and promote the cause of folk music. But in spite of the court ruling, networks and sponsors were still wary. The producers of the new show Hootenany claimed that they wanted Seeger, but that the sponsors weren't willing; and the sponsors claimed they wanted Seeger on the show, but that the public wouldn't stand for it.
Following the do-it-yourself ethic of folk music, Seeger finally decided to start his own show, Rainbow Quest. It began on UHF channel 47 in New York and had only been picked up by seven stations when Seeger began to run out of funds. During its brief run of 38 episodes, Pete talked and strummed with such guests as Elizabeth Cotten, Patrick Sky, Donovan, Judy Collins, and Buffy Sainte Marie. Richard and Mimi Fariсa also appeared on the show in February of 1966.(from Richardandmimi)
