MUSIC QUESTION!

I have a question about a song in the score for Gundam Wing: Endless Waltz.

OK, i have the soundtrack and I have listened to it a billion times, but there is a song that is not on it that is in the movie! The song is an instrumental by the composer of the series Kou Ootani. The song that I am looking for plays when Heero and Wufei are fighting in the atmosphere. It starts when Wufei says to Heero "I will not allow you to go to earth!" and the song continues from there and plays at the beginning of their duel. No I am not talking about the songs "Clash at the stratosphere" or "Battlefield" cuz that isnt what plays in that segment of the movie! Does Kou Ootani have anykind of official website?

If anyone has any information about this lost track or knows where to get it please post here!

Thanks
