Tear Jerker / Man of La Mancha
Quite a few bits in Man of La Mancha, particularly when Alonso Quijana dies. The fact that he dies in a state of euphoria doesn't help matters.
The sum total of the last two scenes, from Aldonza's rendition of "The Impossible Dream," when Quixote remembers who he is and stands triumphantly, to Quijana's death, to Cervantes walking toward the Inquisition while everyone else sings the reprise ... sobbing. Like a little girl.
The two most beautiful songs in Man of La Mancha (to my mind) are "What Do You Want of Me?" and "The Impossible Dream." Of course they just have to also be the most tearjerking.
This is my quest, to follow that star!
No matter how hopeless, no matter how far...
God, "The Impossible Dream". As heartwarming as it can be, it's also tear-inducing.
Especially when Brian Stokes Mitchell sung it for Ted Kennedy's funeral.
Aldonza desperately begging for him to call her Dulcinea again. It doesn't work. At least not at first.
"Aldonza". Watching Quixote's illusions ripped from him is horrible, and you feel so badly for poor Aldonza.
Aldonza: You have shown me the sky but what good is the sky To a creature who will never do better than crawl Of all the cruel bastards who've badgered and battered me, you are the cruelest of all Can't you see what your gentle insanties do to me Rob me of anger and give me despair Blows and abuse I can take and give back again Tenderness I cannot bear.
