First off let me say on behalf of all of us, "Thank you to our men and women fighting for our freedom.  Second, listen to the falsetto!

Paul Leti is his name and he is 21 years old.  He is a U.S. Army Soldier who grew up singing in the church.  Paul was previously deployed in Afghanistan for nine months and just returned home. Paul would use his voice to sing and comfort himself and his brothers and sisters while deployed.

Leti says, "when your out there, it's just being scared of not going home.  You don't know if you are going to see tomorrow, but you have to be brave for yourself, your family, country and friends. "When I was scared music was there." "It feels good that my singing can comfort someone else."

It appeared Paul Leti had missed his cue to start his rendition on Rihanna's "Stay" as pointed out by one of the judges, but he soon began and hits a falsetto at about 4:44 into the clip that sounds incredible.  Paul gets the America's Got Talent Judges to their feet and even gets some hugs from the judges.

Thank you for your service and sharing your voice. God Bless the USA.
