Cubs singer stuns Wrigley Field with an amazing national anthem before Game 6

Before Game 6 of the NLCS, the Chicago Cubs rolled out one of their best national anthem singers.

John Vincent is a Chicago performer known to hold out the note on "free" for an impossibly long time (like this during the NLDS):

He did that again Saturday evening at Wrigley Field, performing an incredible version of the national anthem to the fans' delight and even getting a smile out of the two managers -- Joe Maddon and Dave Roberts.

Watch the video at the top for Vincent's performance (hold out for the big note starting at 1:32).
