The World Cup is now underway with Brazil facing Croatia in Sao Paulo — but not before an absolutely stunning rendition of the national anthem.

You could tell immediately that the players were more into this anthem than what we typically see from athletes.

As is becoming a tradition among Brazilians before big matches, the fans sang the entire anthem in unison with the music stopping about halfway through.

This young fan was the best.

It is easy to see the passion of both the fans and the players.

Afterwards, the Brazilian players were clearly pumped up by what just happened.

Here is the full video. Beautiful.
