Les Bidasses en folie is a French comedy film directed by Claude Zidi released in 1971

Five catastrophe-prone friends—Gérard, Phil, Jean-Guy, Jean and Luis—decide to leave home and start a rock band. They find a supporter in Crème, a young woman who runs a musical instruments shop and believes in them. She enters them in a battle of the bands which turns out to be rigged, but they win despite unleashing mayhem on stage when she cheats on their behalf.
Unfortunately for them, the young men are then called up for their military service. In order to be able to take part in the next competition, they set about being kicked out by being as incompetent and uncooperative as they can be. Their musical talents are however put to use by their commanding officer, who requisitions them to play his daughter's wedding reception. Eventually, the colonel kicks them out with the exception of Gérard, whom he decides to keep as his aide. The other four, briefly delighted to be out, return for him.
