The female voice in song can be a most exciting thing. And none better than the voice of beautiful Welsh mezzo-soprano Katherine Jenkins below. It reduces me to tears. She sings it in the original Italian. Italy has given us much. The best known performance of the song is a duet between Sarah Brightman and Andrea Bocelli at the Piazza dei cavalieri in Pisa but Jenkins has a much more powerful voice. She is, incidentally, a Christian.
