Ryan Krzak (YouTube: RWappin), the creator of popular fan music videos for the Weird Al tracks “Albuquerque” and “Everything You Know is Wrong,” was hired by Al to animate the “Uptown Funk” segment of his latest release, “Polkamania!.” That segment starts at 2:24.
This is similar to how Al liked Jarrett Heather’s “Shop Vac” video, and asked him to animate his track “Word Crimes”. Jarrett Heather, incidentally, is also in this latest video. He animates the “W.A.P.” segment.
The Weird Al-fan dynamic is something more wholesome than can be described. There’s a genuine love there.

He asks for permission from the original artist before parodying a song. If that doesn’t qualify as lawful I don’t know what does.
