The last post in this series looked at the string arrangement in this section of the song.
Now, we add a more traditional synthetic strings and choir sound that fleshes out the original trio arrangement. Certainly cheesy, but good for building a bigger sound with texture. At a certain point, with enough instrument layering, the cheesiness fades away and what you end up with is something thicker and richer than the original trio of instruments.
At least that's what I tell myself.
