Jane Birkin
With the exception of his 1969 international hit duet with Jane Birkin "Je t'aime moi non plus" (where Birkin's erotic voice had turned the song into a novelty success), Serge Gainsbourg was then only a cult figure having mainly met success through versions of his songs recorded by other artists including Brigitte Bardot, Juliette Gréco, Honor Blackman, Jane Birkin, France Gall, Petula Clark and others. The album sold over one million copies in 1979, turning him into a major sensation in France, Belgium and French-speaking Switzerland.
