The Weavers came out of Greenwich Village in the Forties and paved the way for the Great Folk Revival of the Fifties. They were Ronnie Gilbert, Lee Hays, Fred Hellerman and Pete Seeger. Their politics ran from socialist through communist all the way to Maoist. This got them into trouble with McCarthy and got them blacklisted. As a result, when ABC introduced Hootenanny to TV in the Sixties, they were never invited on the show.
