World of Weird Al Yankovic

A while back (4-5 years ago), someone uncovered an article that said Al was going to play accordion on "Pennsylvania Polka," a track from a compilation album about the show The Office. That album never materialized to my knowledge, and there's never really been any solid information on this track. Do you know any details about it, and if it will ever see the light of day?

I know the drummer on that track, but wasn't able to get an answer from him either.
