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.
