Hey, One question. This is the only cheat website i can get on and i was wondering how to get the “immpossible song” for Guitar Hero 3 for playstation 2. I saw it on you tube one time and wondered how to get it. Can you please give me some info. Ill check back every once in a while.

Hey Lucas, do you mean Through the Fire and Flames? If you do then you get it after you beat the game on any difficulty. However, it could possibly be a custom song which you have to download software for your computer and a computer that can burn DVD’s to get.
