Watch: WWII veteran amazes Pearl Harbor crowd with stunning harmonic rendition of national anthem

World War II veteran Peter DuPre played a beautiful rendition of "The Star-Spangled Banner" earlier this week during the pre-game ceremonies of an annual college basketball tournament.

DuPre was one of more than 100 living World War II who were flown to Hawaii to commemorate the 75th anniversary of the attacks on Pearl Harbor by Imperial Japan in Dec. 1941. He was a medic in the European Theatre and participated in the Battle of the Bulge.

The annual basketball tournament — the Pearl Harbor invitational — is held each year to honor all of the more than 2,400 Americans who lost their lives during Japan's surprise attack. It is even held at Bloch Arena, which is on a base that Japan attacked.

DuPre played his rendition of the national anthem prior to Wednesday's matchup between Seton Hall University and the University of California-Berkley.

You can watch his performance below. It's safe to say he brought the house down.
