 There was no scholarly study of French Canadian song until Ernest Gagnon's 1865 collection of 100 folk songs.In 1967, Radio-Canada released "The Centennial Collection of Canadian Folk Songs" (much of which was focused on French-Canadian music), which helped launch a revival of Quebec folk.Singers like Yves Albert, Edith Butler, and, especially, Félix Leclerc and Gilles Vigneault, helped lead the way.
