It's been a while since I played, but if you're referring to the song about the dragon being slain etc., then the sound file should be somewhere in your game directory. Just open it, and listen for the right lyrics, maybe?
Hope that helps.
I am talking about the song which the "ear of the city" in Nightingale Court sings. There isn't any lyric in the directory of the game. And i don't understand what the music talks, so i need the lyric.
