Les Bidasses en folie is a French comedy film directed by Claude Zidi (in his director debut) 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.

Their musical talents are however put to use by their commanding officer, who requisitions them to play his daughter's wedding reception.
