Check out this video. Maybe it'll bring a smile to your face as it does mine, every time I watch it. It's created by a guy from New Zealand called "Pogo". He takes snippets of audio from movies and creates brand new songs from these soundbytes that somehow retains the magic of the movie from whence they came! He's done lots of other songs too. You can see the videos on his official website here. You can even download (for free) a lot of his songs here, (including songs taken from Disney's "Alice in Wonderland", Harry Potter and the Philosopher's Stone, Mary Poppins and more). These downloads made are available with Pogo's permission.
