The Bremen Town Musicians

The cartoon focuses on a Donkey, a Dog, a Cat, and a Rooster and their master Troubadour (much more a classical five-pieces rock-band than a travelling circus). At the start of the cartoon, the band travels to a palace to do a show for the King and his subjects. During the show, Troubadour falls in love with the King's daughter, the Princess, and the band is subsequently thrown out of the palace by the king. Back on the road, Troubadour dreams of the princess and hatches a plan to win the King's consent. That night, the band chances upon a hut housing a band of crooks. Read more on Wikipedia.
