12 is my favorite. Not only does the sunset and the tree match his hair, but the scene's got a real Sound of Music vibe to it:
I go to the hills when my heart is lonely
I know I will hear what I've heard before
My heart will be blessed with the sound of music
And I'll sing once more
The Sound of Music has long been my wife's favorite, leading inevitably to my increased appreciation of it. Two performances of it stand out especially in my memory: the live stage presentation we watched from the front row (gotta score those seats at least once for her!), and Carrie Underwood's live performance on NBC.
And now you have broadened my view.
