Beginning with their debut at the Bitter End in Greenwich Village in 1961, Peter, Paul, and Mary launched a decade of recording songs that would bring socially conscious music to the mainstream. The group is now virtually synonymous with Folk music, but before Peter Yarrow, Paul Stookey, and Mary Travers came on the scene, McCarthyism had forced folk music from the likes of Pete Seeger and Woody Guthrie underground. A decade later, the trio had 11 albums and 12 hit singles, including classics such as "If I Had A Hammer
" and "Leaving On A Jet Plane
," firmly establishing themselves as the most successful Folk music group of all time.
