Thank you for this
To me these are the "3 Magnificent" Tenors.
Enrico Caruso is the Father of the Great Italian Tenors. His personal story is also very touching: he left Italy as a poor man, reached the US and conquered the world, becoming rich and famous. He even had Tiffany make gold coins with his portrait on them. He asked a lot of money for singing, but always did it for free for his beloved Italian people living in America.
Franco Corelli's voice was the most expressive and captivating.
Mario Del Monaco's voice was just the most powerful of them all, no other tenor before, during and after had that unique explosive way of singing.
P.S. John @JCinPA , Mario Del Monaco's "Nessun Dorma" is simply the very best. Another superb performance for you below:
