The song is "Occhi di fata". This one is sung by Beniamino Gigli, but there are many other versions:

"-Please tell me you're going to appeal to my humanity..."
"-Actually, I'm planning to threaten you."
"Well, if you'll excuse me, I have work to do. Evil plots don't just make themselves, you know!"
DEAR Ligeia, Thank you very much for your reply. I'VE BEEN LOOKING FOR THIS SONG FOR NEALY 20 YEARS. THE MYTH IS FINALLY SOLVED. THIS IS ONE OF THE GREATEST SONG EVEN THOUGH I ONLY LISTEN TO WAGNER.
IS "Occhi di fata" ITALIAN FOLK SONG?
Yes, I believe it is.
It was written by Luigi Denza, same composer of Funiculì, funiculà (a very very popular neapolitan song).
"-Please tell me you're going to appeal to my humanity..."
"-Actually, I'm planning to threaten you."
"Well, if you'll excuse me, I have work to do. Evil plots don't just make themselves, you know!"
