"Love Song" Duncan is considered one of Britain's first female singer-songwriters. The live recording of "Love Song" was included on John's
Here and There album. John described "Love Song" as "one of the very few" songs he did not co-author but included on an album earlier in his career. "Love Song" went on to be covered by more than 150 other artists, including
David Bowie. In 2022, both Duncan and John's versions of the song were featured in the folk horror film
Men. This success notwithstanding, and despite their receiving critical acclaim, Duncan's multiple solo albums failed to achieve commercial success. Duncan famously contributed backing vocals to one of the top selling albums of all time,
Pink Floyd's 1973 release
The Dark Side of the Moon, which was engineered by
Alan Parsons. Later, in 1979, she again worked with Parsons, singing lead vocals on the song "If I Could Change Your Mind" for
the Alan Parsons Project album
Eve, in her final album appearance. ==Personal life==
