At the risk of overdoing the effect, I've added music from my end of the world to give the scene a bigger smack at the tear ducts.
I have to say I was quite surprised at how I was lucky to find with the recording I'd used a good deal of musical phrasing meshing well with the lines and even the actors' voice pitch at times.
I'd like to hope that the video does some justice to the emotional weight of the scene. I thought the scenario naturally appropriate to this would be one not involving Lee's death through gunshot.
[EDIT1: The first video was too loud, so I've had to upload a reworked version striking more balance between voice and sound: https://www.youtube.com/watch?v=66qQzpe6nkY
[EDIT2: Have just finished 2 new themes, the first with violins backed by full oriental instrumental ensemble (the best, I think, of all the renditions put up), the second with an abrasively raw nai and some earlier portions of the final scene included. There are some alternative versions of each with different closing music or voice/music synchronisation. The links to those are in the video descriptions
[EDIT3: And one last nai video: http://www.youtube.com/watch?v=t11NrsTqSRA
