The Weavers were an American folk music quartet based in the Greenwich Village area of New York City originally consisting of Lee Hays, Pete Seeger, Ronnie Gilbert, and Fred Hellerman. Founded in 1948, the group sang traditional folk songs from around the world, as well as blues, gospel music, children's songs, labor songs, and American ballads. The group sold millions of records at the height of their popularity, including the first folk song to reach No. 1 on popular music charts, their recording of Lead Belly's "Goodnight, Irene." Despite their popularity, the Weavers were blacklisted during much of the 1950s.
