The cartoons are on a fancy shmancy HD website that will almost certainly convince you to buy...
Make sure to look for "Songs in the Key of HD" at this link, and there you have it. If the link ever fails because BlueRay is trying to take over, you can always visit Ben's site and find quality versions there.
Sorry, it's YouTube, but here are two of Ben's other films that rock people's socks off:
Binge and Purge
Dancing Animals in Love
