Ah ok. So yes there is some of this going on by using bits of TPM score towards the end of the movie.
Yes I did know about the bonus track. The end of the track they used in the TV spots for AOTC. I remember taking not of it at the time but then noticed later (probably once on DVD) that it was absent from the movie.
I seem to recall hearing a classical piece very very similar…maybe by Holst…don’t remember.
