"Can of worms..."
IMO (and it's only my opinion for what it's worth) then if it was a 'roughly' contempraneous release (ie within a few months of the US issue) then it's an Original.
So Jackey Beavers Trying To Get Back To You on Jay Boy (Boy 102) would be fine to play, but Jackie Lee 'Oh My Darlin' Jay Boy (Boy 28) wouldn't.
If it's a different mix/version, therefore there's no original release, then it's OK (ie Deon Jackson on Contemporaries, Montclairs on Contempo).
