Chanter started as a member of a group called the Chanters in 1967 with her sister Irene Chanter and her five brothers, releasing four singles which failed to chart. In 1968, the Chanter sisters became a duo initially known as Birds of a Feather.
The duo released four singles between 1967 and 1972 but none of them achieved chart success. Their first album was Birds of a Feather, released in 1970 and featuring Elton John on piano. The Chanter sisters had appeared as backing singers for John in a Radio 1 session.
Long John Baldry asked the sisters to join his live band in 1973. They also featured on June 1, 1974, a live album featuring Nico, Brian Eno, Kevin Ayers and John Cale, and appeared on the Chris Farlowe album BBC Radio 1 Live in Concert. Both sisters are credited on the 1974 John Cale album Fear and, the same year, Ron Wood's album I've Got My Own Album to Do. Other credits include Manfred Mann's Earth Band's Solar Fire (1973), Nightingales and Bombers (1975), The Roaring Silence (1976) and Watch (1978), plus John Entwistle's Mad Dog (1975), Andy Fairweather Low's La Booga Rooga (1975), Chris Rea's Whatever Happened to Benny Santini? (1978) and Justin Hayward's Night Flight (1980).
In 1976, Polydor released their second album First Flight, although it failed to make any lasting impression. They sang live with John Miles and appeared on a live album. The sisters released two albums in 1978 through Safari Records, both of which failed to chart.
In 1971, both sisters were cast as schoolgirls in the Hammer film Twins of Evil.
