What did Neal E. Boyd sing on America's Got Talent?

Question

Just saw the clip on Yahoo and wanted to know what song that was

Answer 1

I think the song's called "Nessun Dorma."

Answer 2

Yes, it is "Nessun Dorma" -- it's from Puccini's opera "Turandot".  It means "None shall sleep!"

The lyrics are quite beautiful -- it's a fairytale setting where the "evil" princess has proclaimed no one in the town can sleep until the hero reveals his name (she wants to get out of marrying him).  The hero sings "No one will sleep, my secret is hidden within, no one will know my name."  The ending phrase victoriously proclaims (he's held out all night without revealing his name) "Vanish, O Night -- Set Stars, set stars.  At daybreak, I shall win!  I shall win!  I shall win!"
