He then mixed in the entertainment world by working as a lighting technician, a master of ceremonies in several Montreal cabarets and, for a short time, as a bodyguard to Québécois singer Michel Louvain.
In 1969, Lautrec definitively abandoned the yé-yé style with the release of songs like Eloise, Hallelujah (The Flowers of the Sun) and Hosanna, a French-language interpretation of Neil Diamond's Holly Holy.
Their partnership led to recording the album Fluffy whose track list consists exclusively of Québécois compositions, including Plamondon's Le mur derrière la grange (The Wall Behind the Barn), which became a hit in Quebec.
In 1985, Donald Lautrec became the owner of the production company Riviera, which produces Quebec quiz shows such as Charivari, Action et Reaction and Double Jeopardy.
He withdrew from the entertainment scene for about twenty years and unexpectedly returned in November 2009 with a new album of songs, Lautrec A Jamais, which was well received.
