The event marks the 100th birthday of World War II veteran William "Bill" Fly.
Fly's home was destroyed by Hurricane Harvey, but an online campaign raised more than $70,000 to help him.
"I can't believe that they would help someone like me," Fly said. "They've got to be sent from heaven or something."
