speak softly love

I love this song, especially at the time this song was played when Michael was getting "hit by thunderbolt" upon seeing Apollonia.

-- Updated much later:
It turned out that there was no song played in that scene above. I guess it must have been played in my head.
~~~~~~~~~~~~~
Speak softly love and hold me warm against your heart
I feel your words the tender trembling, moment starts
We're in a world, our very own, sharing the love that only few have ever known

Wine-coloured days, warmed by the sun
Deep velvet nights, when we are one

Speak softly love so no one hears us but the sky
The vows of love we made will live until we die
My life is yours, and all because you came into my world with love so softly love....

sung by Andy Williams
Godfather's theme song
