In the early 1960s, Claude François joined the exclusive circle of yé-yé idols. Settling in Paris in 1961, the artist, determined to take the capital by storm, recorded new songs for the Fontana label. A few months later, the thunderous success of 'Belles! belles! belles!' was soon followed by 'Si j’avais un marteau', an adaptation of folk songwriter Pete Seeger's hit.
Coined by sociologist Edgar Morin, the term "yé-yé" refers to a generational movement inspired by Anglo-Saxon pop culture. Adored by post-war baby boomers, its protagonists caused a popular tidal wave and shook up the charts.
