What is the name of the song in Shawshank Redemption, which Morgan Freeman was talking about?

It was the scene where the main character locked himself in the
office, and played the song of the 2 Italian ladies through the
loudspeakers of the prisons. And Morgan Freeman was talking about how
sweet the song was. What is the name of that song sang by the 2
Italian ladies. Please help me out with this. I am so obsessed with
listening to the whole song.
