In 1974 Hustin's self-penned song "Fleur de liberté" ("Flower of Liberty") was chosen as Belgium's representative in the nineteenth Eurovision Song Contest, which took place on 6 April in Brighton, England. The 1974 contest is notable for the participation of a number of artists who were already internationally known names (Olivia Newton-John, Gigliola Cinquetti, Mouth &amp; MacNeal), also as the contest which served to launch the winning group, ABBA, into global superstardom. In this very competitive field, "Fleur de liberté" finished in ninth place of 17 entries.
