Wire connection

[casandra]

Hi guys,
This is my first post and i really need help with a ceiling light fitting which i hope to put up. I am replacing an old fixture( this one was there when i moved in) and have come up with the problem with connecting the wiring correctly, out from the ceiling there are TWO grey cables and each have three wires coloured Red, Black and a copper wire (no casing). My new fixtures transformer is double insulated and does not need to be earthed, the fixture is wired with just a live supply wire and a neutral wire (blue and brown) could some one please guide me out of this muddle and advise me what wires need joining and what i do with the others.

Thanks in advance
