You can fit a lot of people into Wrigley Field, but that number can never be described as "millions."

So Friday's rendition of "Go Cubs Go" at the team's World Series celebration in Grant Park might have just been the biggest ever.

Country singer Brett Eldredge, a friend of Cubs players Anthony Rizzo and David Ross who celebrated the Cubs winning the World Series at Game 7 in Cleveland, took to the stage at the conclusion of Friday's rally and led the crowd of millions in the victory song.

It was pretty awesome, and you can check it out in the video above.
