Paddington Surprise Animation

I'm looking for an animated video clip to reveal a birthday surprise. The animation should be fun and playful telling someone that they are going to see the Paddington musical. Ideally we would be able to use a clip of a song from the show as the background music. It would be good to open with the attached image as a flyer fluttering down then the rest of the animation starts. Please include samples of similar work in your bids.
