[1] Their first, self-titled album was released in 1977; by the end of the decade they were one of the biggest French rock bands in the world, opening shows for The Rolling Stones in Paris, Quebec, the United States and Japan.

Among their best-known songs are "Hygiaphone", "Métro c'est trop" ("Metro's Too Much"), "La bombe humaine" ("Human bomb"), "Argent trop cher" ("Money Too Expensive"), "Ça c'est vraiment toi" ("That Is So You"), "Cendrillon" ("Cinderella"), "New York avec toi" ("New York City With You") and "Un autre Monde" ("Another World").

The band reunited briefly for a concert at the Point Éphémère on 11 September 2015 under the name "Les Insus" (pronounced [lezɛ̃sy]; insupportables, meaning insufferable.

The elided name also suggests the word portable, meaning "cellphone" in French, thus implying an upgrade to modern times).

Les Insus was composed of Aubert, Bertignac and Kolinka but with the bassist Corine Marienneau replaced on the bass guitar by Aleksander Angelov (hence the reason they were not able to use the name "Téléphone").
