Odd wiring in ceiling light fitting

    I've removed a ceiling light fitting in the bathroom of my 'new' (built
    c.1960) house, and I'm a little confused by the wiring - perhaps someone can
    suggest what is going on -

    The ceiling light fitting has three terminals, of which one is not used and
    the other two have black wires running to them - one each. The two red wires
    are joined together and insulation taped. The two earths are also twisted

    The light works fine and switches on and off with a pull-cord switch located
    elsewhere in the room.

    The problem is, the light fitting I am replacing it with has a Live and
    Neutral side, and I don't know which wires to put in each side - I tried the
    two blacks, one in each side (as per the current light), nothing happens -
    then tried the two blacks in one side and the two reds in the other - the
    light comes on, but permanently on irrespective of the switch position.

    Any suggestions gratefully received.

    Sorry, should have added - I am in the UK.
