Nope.
Apparently he wanted to but the record company wouldn't let him.

*EDIT* "In 2010, an expert appointed by a court stated that the voice of Lou Deprijck, the composer/producer of "Ça plane pour moi," on a record from 2006 is the same voice as on the original 1977 recording. "Today it appears from the report of the experts that the voice of 'Ça plane pour moi' is Lou Deprijck's voice," stated the newspaper La Dernière Heure on Monday, 26 July 2010. Plastic Bertrand previously disputed the allegation, but on 28 July 2010 the singer finally revealed that he is indeed not the singer of any of the songs in the first four albums released under the name Plastic Bertrand."
