Listened to this again on my way to work. (I have a one hour commute so I have time for these kind of things). Comparing it (the orchestra version), to the studio version #12 on the soundtrack CD. I really love the ascending "Why, why. why's" in the studio version, but I have to say, the orchestra version is stellar. The song starts off with "fluttering" violin strings, (which is fantastic), then, she starts to sing about "There's no chill, but yet I shiver", and the strings are fluttering like shivering, very timidly. Then, at the part of the song a few lines later she sings about "being weak one moment and the next i'm fine." During this part, the music gradually goes into strong confident bold chords that you would associate with strength.

This version was brilliant- and now I think I understand why she chose this one to be the one in the movie. (I think it was this one.)

Oh, and the instrumental solo in the middle- it just transcended me to another dimension. Then her voice comes in and it sounds like an orchestra instrument itself blending almost like a high string note on a violin or some kind of high horn note.

Then, I wondered if she had ever considered adding the ascending "Why, Why, whys" from the studio version to the orchestra version? OMG, that would have been awesome to combine the two at that point! I played the two versions over and over and by the time I got to work I was literally high off that music. Music is wonderful isn't it?

Ok, I now know how Beethoven got 33 variations! lol
Music is alive and constantly evolving or can evolve.
