Françoise Hardy. Wolfsohn asked Dutronc to work with Jacques Lanzmann, a novelist and editor of Lui magazine, to create songs for a beatnik singer called Benjamin. Benjamin released an EP in 1966, featuring songs written with Dutronc and a Lanzmann-Dutronc composition, "Cheveux longs" (Long Hair). However, Wolfsohn was disappointed by Benjamin's recording of a song titled "Et moi, et moi, et moi". A second version was recorded, with Dutronc's former bandmate Hadi Kalafate on vocals. Wolfsohn then asked Dutronc if he would be interested in recording his own version. The single reached number 2 in the French charts in September 1966. Cultural historian Larry Portis describes the arrival of Dutronc on the French music scene, along with that of Michel Polnareff at around the same time, as representing "the first French rock music that can be considered a musically competent and non-imitative incorporation of African-American and African-American-British influences". For Portis, Dutronc marks a break with the literary tradition of French chanson in his creative use of the sounds, rather than just the syntax, of the language. Dutronc's self-titled debut album, released at the end of 1966, sold over a million copies and was awarded a special Grand Prix du Disque by the Académie Charles Cros, in memoriam of one of its founders. A second single, "Les play boys", spent six weeks at number one and sold 600,000 copies. Dutronc was one of the most commercially successful French music stars of the late 1960s and early 1970s. During that period, he released seven hit albums and more than 20 singles, including two further number ones: "J'aime les filles" in 1967 and "Il est cinq heures, Paris s'éveille" in 1968. According to music critic Mark Deming: "Dutronc's early hits were rough but clever exercises in European garage rock...like Dutronc's role models Bob Dylan and Ray Davies, he could write melodies strong enough to work even without their excellent lyrics, and his band had more than enough energy to make them fly (and the imagination to move with the musical times as psychedelia and hard rock entered the picture at the end of the decade)". 1970s Most of Dutronc's songs up to 1975 were written with Jacques Lanzmann, with only two written solely by Dutronc. Lanzmann's wife Anne Ségalen is also credited on some songs. Dutronc wrote three songs with comic-book writer Fred, whose stories he also narrated for commercial release in 1970.
