No Harmony for Beeswax - S4.E24

Beeswax thinks that the origin of perfect organization of ants is their singing. So, he steals their song. It's a copyright for ever : the ants can't sing that song anymore. The ants are depressed (furthermore it's a special day : they have to parade in the meadow). How will they now patrol without their source of rhythm and above all without the motivation of this song ? Maya will help them.
