Fans of Civilization 4 will be familiar with Baba Yetu, the official theme song of the game. The song is the work of composer Christopher Tin, who won a Grammy for the song making Civilization 4 the first-ever video game to win the highly-coveted music award.

Now, in an episode of America's Got Talent, Baba Yetu was sung in front of the judges by the Angel City Chorale. Of course, its unlikely that the panel would be familiar with the song from Civilization 4, but that didn't hinder their love for the performance. In a wild turn of events, the Golden Buzzer was pressed, which means that the chorale will make it through the live show.

The diverse choir stunned the audience with "Baba Yetu" and earned guest judge Olivia Munn's Golden Buzzer. " Get The America's Got Talent App: http://bit.ly/AGTAppDownload " Subscribe for More: http://bit.ly/AGTSub " Watch America's Got Talent Tuesdays 8/7c on NBC!

As far as I can remember, this is the first time that a song written for a video game ever made it to America's Got Talent or any other talent show out there. I may be wrong, so let me know in the comments below if this has happened before.
