In 1977, Prévost entered the French Eurovision selection with the song "Pour oublier Barbara", but failed to progress from the semi-final. The following year, his song "Il y aura toujours des violons" ("There Will Always Be Violins") was chosen as the French representative for the 23rd Eurovision Song Contest. Strangely, the song only finished second in its semi-final before emerging the clear winner in the final. As a result of Marie Myriam's victory for France the previous year, the 1978 Eurovision was held in Paris on 22 April. Although "Il y aura toujours des violons" was a very traditional, old-style ballad with no concession to the musical trends of the late 1970s, it finished the evening in third place of the 20 entries.
