[This is the third year I've posted this clip on Christmas Day. It's a perfect way to celebrate the holidays!]
I get chills every time I hear Deanna Durbin's low-key, but lush performance of Silent Night. It's from the murder mystery-musical-comedy-noir (and how many of those exist?) Lady on a Train (1945). While she sings to her father to ease the pain of being apart on Christmas Eve, even the thug listening at the door is moved to tears (though he still goes through with the secret theft his shifty boss has ordered). Given the underlying threat of danger, it's an oddly peaceful, heartwarming scene.
