trailer music head in the clouds

Hello,
Is there any one who knows what music was used in the last part of the trailer ?
It is beautiful but it's a mystery to many (soundtracknet, forums like adtunes,etc etc )
Or is there someone who knows how i could contact the movie's composer terry Frewer ? (maybe the trailer music is from the movie itself)
I have searched for months now
Please let me know
[email protected]
thanks very much
Paul
