That's My Piano, Sir! - Wolfgang Amadeus Mozart

Travel through time following a charming little mouse called Minim who loves cheese and music. One day, he witnesses the arrival of a dapper, young Mozart and his family as they set foot on a dock one late, cold night. He is no ordinary boy, sporting a white wig and dressed in red velvet, on his way to playing several concerts in the city. To the surprise of all, he begins to play with his sister for the tired customs officer and gloomy dockworkers.
The evening air comes to life, and soon, everyone's faces are beaming, their ears ringing with music! Recorded excerpts of the composition "A Little Night Music" ("Eine Kleine Nachtmusik") are included.
