Can anyone give me a download link or something so I can download the Halo 3 Piano

[I can Help!]

Soundtrack? I really like the piano soundtrack in Halo 3, the one that is played when you are at the main menu, and I'm wondering if anyone knows where I can get it. I've found it on YouTube and things, but they're all to low quality and they aren't the actual composition that was made first.

Please help, I really like this music and I would really appreciate it if someone could help me!
