In person post-match songs?

I am attending a USMNT match for the first time during this world cup and don't keep up with what the Outlaws do. After the match, win or lose, are sticking around to sing any songs? "America the Beautiful", "God Bless America", or "My Country 'Tis of Thee" perhaps? Something less patriotic but still American, like "Sweet Caroline"?

Something... anything... to unite the people and create a bit of a chill for just a brief moment.
