Originally part of the movie Make Mine Music, this cartoon was released later on its own as a theatrical short. This is a showcase for Nelson Eddy, who does the narration, voices of the characters, and all the singing. The story is about a whale named Willie that is heard singing by the crew of a ship at sea. As reports spread about Willie, opera impresario Tetti-Tatti is convinced the singing is actually coming from an opera singer the whale must have swallowed. He sets out to hunt and kill Willie to prove this. What follows is a bittersweet and somewhat allegorical story with a surprisingly dark end. It's a good cartoon with nice animation and impressive vocals from Eddy. Not sure how the ending will play for little ones, though.
