Britain's premier session vocalists throughout the 1960s, The Breakaways also recorded a handful of little-known girl group singles.
Back in London they left Ford to sing backup for Joe Brown who Vicki Haseman had been engaged to for a year.
Most notably this was on Clark's international hit, "Downtown" (not only the original English version, but also in French, Italian and German).
There followed "I Know a Place", "Round Every Corner", and "A Sign of the Times", and on several of Clark's most successful French recordings, among them "Je me sens bien auprès de toi", "Mon bonheur danse" (a vocal version of The Shadows' "Foot Tapper") and "Tu perds ton temps".
They backed Cliff Richard's performance of Congratulations in the 1968 Eurovision Song Contest at the Royal Albert Hall in London, which placed second in the competition.
In 1977, at the Eurovision contest staged at the Wembley Conference Centre, the trio sang backing vocals for the Israeli entry Ahava Hi Shir Lishnayim performed by Ilanit.
