Desperately need the soundtrack, help.

Does anybody know where I can get hold of this soundtrack? the only copies I can find anywhere are going for silly money on ebay.
I personally am not the worlds biggest fan of this film (certain kitsch value I guess) but my girlfriend loves it like you wouldnt believe, and if I could get hold of it for her, copy, original anything I would most definately be her hero for ever.
So help a guy out friends, please.....
