Yé-yé was a style of pop music that emerged from France, Québec and Spain in the early 1960s. The term "yé-yé" derived from "yeah! yeah!" The style expanded worldwide, due to the success of figures such as the French singer-songwriter Serge Gainsbourg.
The yé-yé movement had its origins in the radio programme Salut les copains, created by Lucien Maurice and hosted by Daniel Filipacchi, which was first aired in December 1959. In fact the phrase "Salut les copains" dates back to the title of a 1957 song by Gilbert Bécaud and Pierre Delanoë, who had little regard for the yé-yé music the radio show typically featured. The program became an immediate success and one of its sections ("le chouchou de la semaine" / "this week's sweetheart") turned to be the starting point for most yé-yé singers. Any song that was presented as a chouchou went straight to the top places in the charts. The Salut les copains phenomenon continued with the magazine of the same name which was first published in 1962 in France, with German, Spanish and Italian editions following shortly afterward.
