DuPré is no stranger to performing the \"The Star Spangled Banner\" at high-profile sporting events.

He turned energized soccer fans at Red Bull Arena in New Jersey silent in May when he performed the national anthem before the U.S. Women’s National Team's game against Mexico.

The U.S. players also visited Normandy with DuPré and three other World War II veterans in January while in France ahead of the 2019 World Cup, which the U.S. team went on to win.
