There are some arrangements in cut scenes that haven't been released, is there any way to get our hands on them?

For example: http://www.youtube.com/watch?v=wyNP0w6Cw4Y - 7:45 onwards. A rearrangement of "As a man, as a brother".

Or: http://www.youtube.com/watch?v=vE5QQNHqNSY - 7:50 onwards. A rearrangement of "Fly".

If anybody with influence knows any way of getting our hands on this, it would be fantastic.

Thanks in advance!
