Unless I'm mistaken, there's only one version isn't there? What are we supposed to make a mix out of? Give us something to work on, and maybe someone will take you up on it. :)
No, it's not a wind up. To make a mix usually requires two or more versions of a song, i.e. an intrumental version, perhaps an existing 12" mix, or a 5.1 version, which the channels can be isolated from, so that the mixer actually has something to 'mix' together. I don't believe, although I stand to be corrected, there is more than one version of WDWTA, so apart from a bit of pointless cutting, pasting and repeating bits of it, there's nothing to make a mix from. Oh, I think there might be a live version somewhere, but live / studio mixes don't usually work very well. This is why only selected tracks from the Queen catalogue have so far been attempted by mixers.
Of course, I'm only speaking for myself here. If someone wants to have a go at this - good luck!
There's a rather silly [for lack of a better word] single edit of the track. Then there's the VH1 live version with the two guitar solos. I suck at remixing, otherwise I'd attempt a dance remix...

Why doesn't someone try messing with the original track in Audition and see what's there? That might give some interesting elements to work with. You could even mix up the track by using certain bits in the middle of the song to start it off. Or even add someone else singing. Who knows?! I think this is for the more experimental person on here.
Peace,
Adam.
