Call me crazy, but a fraction of that performance sounds strikingly similar to "I'm Looking Over a Four Leaf Clover". I mean, I get it, he's Oswald the Lucky Rabbit, but I wonder what other musical numbers inspired the whole number.
In the old cartoons, Oswald's girlfriend was sometimes a bunny and sometimes a cat. When they brought Oswald back in Epic Mickey, they decided on using the cat and named her Ortensia. It's stuck since then.
