A Pennsylvania high school soccer team wasn't going to let staffing problems silence the national anthem.

When the person who normally plays a recording of the "Star Spangled Banner" wasn't at the stadium at Greater Johnstown High School, the players stepped in and brought their voices together for the pre-game song, WJAC reported.

"Our person that normally plays the national anthem wasn't there. We didn't have anyone to play it, so we started to sing it instead," Michael Marino said.

Teammates said it was Justin Wiesheier's idea.

"Well, the national anthem, they said, is not going to be able to be played tonight. I said you know every sport has to have the national anthem, so I started singing the national anthem, and before you knew it the whole team was singing, and everybody rose and looked at the flag," Wiesheier said.

He said it was just instinct, and the video of the team singing was posted to social media, going viral.

Parents said it was a proud moment as they watched the boys honor America, WJAC reported.

"You should feel proud to live in America. Even if it's not going to play, you should still sing the national anthem before a sporting event or anything really. We start the day with the Pledge of Allegiance, why wouldn't we start football games or soccer games with the national anthem," Lukas Enos said.
