The trio, consisting of Peter Yarrow, Noel Paul Stookey, and Mary Travers, was known for their melodic, multi-voiced interpretations of other artists such as Bob Dylan, Paul Simon, and Pete Seeger, but they also wrote their own material.
PP&M, as the group was often called, was strongly engaged in the peace and civil rights movement and performed Dylan's "Blowin' in the wind" in Washington in March 1963, where Martin Luther King held his famous "I have a dream" speech.
During the group's heyday in the 1960s, they topped the Billboard charts on several occasions, including with John Denver's "Leaving on a jet plane", and won five Grammys. The song "Puff the magic dragon", which Yarrow co-wrote, became the group's biggest hit.
The group disbanded in 1970, but reunited later and stayed together until Mary Travers' death in 2009. After her passing, Yarrow and Stookey continued to perform both separately and together.
Peter Yarrow died of urinary tract cancer, which he had been suffering from for four years, according to the group's publicist Ken Sunshine.
