"

In 1971, a boyfriend of Cameron's was killed in a car crash and she retreated for some time to live in Yorkshire.[citation needed] In 1972 she returned to London and started to work as a film researcher, moving into a flat in Pimlico and virtually retiring from singing. She died in her home on 3 April 1980, having apparently choked to death while eating. An obituary in a 1981 issue of Folk Music Journal stated that she "died after mis-swallowing some food."[1]
