The Mamas & the Papas were an American-Canadian folk rock vocal group that recorded and performed from 1965 to 1968, with a brief reunion in 1971. The group was a defining force in the music scene of the counterculture of the 1960s. Formed in New York City, the group consisted of Americans John Phillips, Cass Elliot, and Michelle Phillips, and Canadian Denny Doherty.
