I was reading about every Al single released in the Weird Al Wiki and it said that there's an alternate version of "Smells Like Nirvana" exclusively in the canadian release of the single. I couldn't find it online so I just asked Al's guitarrist Jim "Kimo" West" if it's true or not. The only thing we have to do is wait for him to reply(Which his website says that he usually takes 1 or 2 days to do that).
