well i just got the one from AU and it’s exactly the same. this leads me to believe that they only pressed one version. it’s curious, the blue writing on the cassette, typically means AU, but they stuck it in a UK sleeve.
unless a true AU one turns up later, i think there’s just the one version.
but, on a sidenote, i did find a bwbw au cassingle last week. it’s a little xmas present to myself.
