Gainsbourg says that it was incorporated into an infantry regiment in 1948, fodder and disciplinary regiment, where he became a sniper in the light machine gun.
I remember at that time a good friend whose father, former sergeant of the 1st REP, paras with other comrades, decided to express their opposition to what they thought was a caricature of the Marseillaise in full concert Gainsbourg. Warned it away to deflate, invited them to express themselves. He maintained that he respected them as the Marseillaise he had wanted to erect a modern version, not in the manner of Giscard, but personal, French, patriotic. France, the country of the universality of human rights - Reggae marriage (what a sound!): A great success.
Thank you the artist.
