Magny became increasingly supportive of political activism. Her song "Le mal du vivre" was banned by ORTF, the state broadcasting network, and marked her out as France's first protest singer. Her recordings were issued by Le Chant du Monde. Her next album, also self-titled, featured her songs "Vietnam 67" and "Viva Cuba", together with one celebrating a strike of port workers, as well as further settings of poems and metaphysical texts. During the events and riots of May 68, she actively supported students and workers at sit-ins and through benefit concerts. She wrote the song "Les militants" for the protesters, and later also issued a spoken word album, "Magny 68/69".
