At that time, Wolfsohn was looking for a female singer to record "Oh oh chéri", a French-language version of Bobby Lee Trammell's song "Uh Oh". After an audition in person, Wolfsohn immediately offered her a one-year contract, which she signed on 14 November 1961. Upon learning of Hardy's new record deal, Mireille Hartuch presented her student at the Petit Conservatoire TV show on 6 February 1962, in what has been described as "one of the most popular French TV extracts of all time". In a much remembered exchange, the hostess asked the young singer what the English-language "yeah! yeah!" in her lyrics meant, after she performed "La fille avec toi" on her guitar. The transliteration "yé-yé" was later popularized by sociologist Edgar Morin through an article published in Le Monde on 7 July 1963, in which he analyzed the burgeoning youth-led pop music scene. The yé-yé phenomenon was spearheaded by the massively popular radio program Salut les copains—created by Daniel Filipacchi—and a successful magazine of the same name. Recorded in the spring, Vogue released her first extended play in May 1962, which included "Oh oh chéri" along with her own compositions "Il est parti un jour", "J'suis d'accord" and the sentimental ballad "Tous les garçons et les filles", which despite her wishes was relegated as a B-side because the label deemed it too melancholic for young audiences. On 5 June 1962, the singer proudly shared the record sleeve at the Petit Conservatoire. In early October, Hardy filmed a black-and-white music video for "Tous les garçons et les filles" directed by Pierre Badel, which aired on TV show Toute la chanson. The song was chosen at the initiative of Hardy and the show's producer André Salvet, despite Wolfsohn's reluctance to promote it. Hardy was introduced to the large majority of French people on the evening of 28 October 1962, when the clip was rebroadcast during an interlude of the televised results of the presidential election referendum. The exposure propelled the song to widespread popularity among young people—particularly teenage girls—aided by the wide airplay it received by radio stations, starting with youth-favorite Europe n° 1. "Tous les garçons et les filles" was further popularized by a Scopitone music video directed by Claude Lelouch, which shows the singer in an amusement ride alongside two girls whose skirts are lifted up by the wind. Building on the momentum generated by the song's success, Vogue
