After transcribing "Unforgotten" into a full score, I decided to do it again for the updated version, "Never Forget". I did it to the best of my ability, had to guess on some things, but I played it side by side with the Halo 3 CD and it sounded pretty darn close, if not exact, to me. So I think I got it right. Also, at measure 25, I couldn't quite pin down which key Marty switches to so I just left it in G Maj/E min. until measure 51 when he obviously goes back to the original key of "Unforgotten" (which is A flat Maj/F min). Any question you have, I will be happy to answer to the best of my ability. Enjoy.
