The Song Swappers sang backup for
Pete Seeger on four
reissue albums in 1955, when
Folkways Records reissued a collection of Seeger's pro-union folk songs,
Talking Union. Travers regarded her singing as a hobby (she worked full-time as a dental technician) and was shy about it, but was encouraged by fellow musicians. The group Peter, Paul and Mary was formed in 1961, and was an immediate success. They shared a manager,
Albert Grossman, with
Bob Dylan. Their success with Dylan's "
Don't Think Twice, It's All Right" helped propel Dylan's ''
Freewheelin''' album into the U.S. Top 30 four months after its release. Peter, Paul and Mary broke up in 1970, shortly after having their biggest UK hit, singer-songwriter
John Denver's ballad "
Leaving on a Jet Plane" (originally titled "Babe I Hate To Go") (
UK No. 2, February 1970). The song, which reached the top of both the U.S.
Billboard and
Cash Box charts in December 1969, was the group's only number one hit. Travers subsequently pursued a solo career and recorded five albums:
Mary (1971),
Morning Glory (1972),
All My Choices (1973),
Circles (1974) and ''It's in Everyone of Us'' (1978). The group reunited for one night in June 1972 to take part in a special fundraising concert at
Madison Square Garden for presidential candidate Sen.
George McGovern. Peter, Paul and Mary re-formed in 1978, toured extensively, and issued many new albums until Travers' death. BBC television recorded their performance at the
Southport Theatre in 1983. The group was inducted into the
Vocal Group Hall of Fame in 1999. ==Personal life==
