My copy somehow ended up going through Manships hands, he had it on his site described as having a large felt pen circle on one side,
in my dafter days (if that's possible ) I put this marker on to show it was mine, done on turntable whilst running so a very large circle,
after martyns post I'm doubting my mermory a little now because i also had I Like to Party and this was defo red/white one side, red/blue the other.
