Applause: The Weavers At Carnegie Hall

Before there was The Kingston Trio and the folk revival of the late 1950s, which became a protest song movement in the 60s, there was The Weavers, a folk group founded in Greenwich Village in 1948. All four members were seasoned lefties: Pete Seeger, Lee Hays, Ronnie Gilbert and Fred Hellerman. Incredibly enough, they had some pop music hits before they became blacklisted in the early 50s. This 1955 reunion concert at Carnegie Hall instantly sold out and was recorded live. It's my all-time favorite live concert album.

There's a very good documentary about The Weavers, called Wasn't That A Time.
