I don't know who did the tune but it's one that freaks me out completely. I once watched a horror movie where the killer whistled the tune whilst cleaning himself up after killing people. And ever since then I just feel creepy when I hear it. It's the same with the Halloween tune. I go all goosebumpy.
Like you I'd like to know who actually made it so I can stay well clear of it.
If you want to confirm for yourself one way or the other, there's a polyphonic version of it here -
Does sound very similar to Alpha Beta Gaga though...
