L’infidèle had already been written for some time when Dubois recorded it in 1974 at Bearsville Studios outside Woodstock, N.Y., where Bob Dylan had once recorded his mythical album with Canadian group The Band. L’infidèle was recorded with such session musicians as the Mothers of Invention’s Billy Mundi on drums and Toronto musician Richard Bell on keyboards. Both this piece and the En voyage album were produced by Utopia member Jean-Yves Labat.
In 1995, L’infidèle became a SOCAN Classic after reaching 25,000 airplays. Dubois’ song received the same award 20 nearly years later, in 2004, in a new version by Stéphanie Lapointe for the popular reality television show Star Académie that gave the song a second life and maintained the #1 position on the Quebec Francophone Top 100 chart from May 31 to July 26, 2004.
The piece also received a SOCAN Pop Award in 2005.
In 2007, Patrick Bruel and Claude Dubois performed the song together as part of the tribute album Duos Dubois.
