About this sound
This is a 5-second musical clip of Marc Rebillet chanting and singing the line about wanting to be let in, delivered like a looping plea at a closed door. It feels desperate, cheeky and pushy in a playful way, turning a simple request to enter into an over-the-top demand that keeps repeating until it becomes funny.
