In 1966 she was contracted to Pathé-Marconi and released her first single "Garçon manqué". In 1968 "Papa vient d'épouser la bonne" sold a million copies and was a major hit. Dani was meant to have been France's Eurovision Song Contest 1974 entry with the song "La Vie à 25 ans", but President Georges Pompidou died in the week of the competition, so she never entered Eurovision properly. Her only English language record release to date is "That Old Familiar Feeling", which has the same music as "La Vie à 25 ans" but with English lyrics by British singer-songwriter Lynsey de Paul.
