When was this released?

I recently bought the 'Black Wax' 12" which contains the Queen Bee remix of Another One Bites The Dust. Because I am a complete geek I keep a list of all the items in my collecttion. Does anyone know which year this was released and in which country? I don't like to see gaps in my list!

Thanks

If we talk about the same release then it's ABBA/Queen promo 12" by Black Wax label, which is unofficial UK release, cat.number BW1 (thus making it their first release). No more details, sorry.

Yes that is the one. As it is unoffical I guess I could upload it, unless it has already been shared?
