The Bremen Singers

When Rooster, Cat, Dog and Donkey must flee their homes, they feel afraid and alone in the world. They meet on the road and are surprised to find others in a similar situation. They quickly become friends. The rooster has the idea of going to Bremen to become a busker, since he has such a good voice. The others assure him that they, too, are musical, with good singing voices, and form a quartet!
On the way to Bremen, they spy a house, off-road, in the forest. They had just been thinking about shelter for the night. Maybe they can sing for their supper, too. But the house is the hideout of a gang of robbers, who are not likely to welcome passing travellers.
How is it, then, that the four friends are able to take possession of the house, and live there, peacefully, for a while? Suddenly, everything changes when visitors arrive. Is it for the better?
