The Portuguese-Belgian singer slipped away during an interview on the Portuguese revolution of 1974. Lio then spoke about the liberation of women's voices.

In 2006, Lio had, during the program "Everybody talks about it," denounced the death of Marie Trintignant at the hands of Bertrand Cantat: "I think that Bertrand is entitled to redemption, but to say that Marie was responsible for her death with him, no, love does not bring death, or it's a mistake." She responds succinctly: 'Despite him. Despite this man (Thierry Ardisson) who is a manipulator and whom I do not respect. We won't know more.' She pays tribute to "Adèle Haenel, who paid very, very dearly" for her voice. 'Judith Godrèche now benefits from a better heard voice,' she assures the interpreter.
