Reminded me of a song .. :)

I am so sorry this question is not related, but actually the movie reminded me so much of a character singing " It had to be you " in another movie. I just can't remember the name of the movie or the characters or anything, but I can never forget that voice and how beautiful it sounded .. All I can remember is that it was so sad, like a death or something. It had no music, just singing.

Please if you have any insights or know anything related, post, thank you :)
