Jean Constantin was primarily active during the 1950s and '60s in the music and film industries. Charles Aznavour's "À T'regarder" (1955) and Zizi Jeanmaire's "Mon Truc en Plumes" (1956) were among the first instances of his songs becoming popularized. Edith Piaf's 1958 performance of "Mon Manège à Moi (Tu Me Fais Tourner la Tête)" would become the most enduring instance of his craftsmanship as a songwriter. Perhaps even more enduring is his soundtrack for François Truffaut's Les Quatre Cents Coups (The 400 Blows), one of the defining films of the French New Wave movement. Despite his success as a songwriter and composer, Constantin had little success as a singer. ~ Jason Birchmeier
