As the Stanley Cup celebration continued, fans at Wrigley got a glimpse of the trophy.
Between Cubby blue and Sox black, there also was a lot of red starting to fill the Friendly Confines.
"I'm a true Cubby fan. He is a true Sox fan," said Rose Boyden. "Once we heard the Hawks were going to be here, we were like, 'We're going.'"
Sunday, the Crosstown Classic took a back seat to the 'boys of winter.'
"That is the only thing that unites us, besides our parents," fan Al Bitoy said.
With the rain threatening the ceremony, suddenly it stopped, a rainbow was seen above Wrigley, and minutes later, the Stanley cup champs and the cup were out on the field.
Passing the cup around, the Hawks paraded around Wrigley to screaming and camera-ready fans, high-fiving some who were lucky enough to have front row seats.
By the time cup reached home plate, Blackhawks Coach Joel Quenneville took it over, carrying it from one dug out to the next.
When White Sox Manager Ozzie Guillen hoisted Lord Stanley's Cup over his head. The jubilant tone took a turn, cheers to jeers.
But all was forgotten when the Hawks and the Cup took to the pitcher's mound. Stanley Cup's most valuable player, Jonathon Toews, took the ball and handed to former Cubs president and now Hawks president, John McDonough, who threw out the opening pitch.
Ryan Dempster, who is Canadian and a big hockey fan, caught it.
"This is something you'll never see in a lifetime, just amazing" Dempster said.
But the ceremony wasn't over. In what proved to be a touching moment in Chicago sports history, the North and South sides came together as one with the Chicago Blackhawks.
"I never thought anything like this would happen. This is a great moment," said Marian Hossa, Blackhawks player.
"Once in a million," said Maryann Kane. "This is it. I can go to my resting in heaven. Best day of my life."
Fans say that moment --with all three teams together on the mound-- was something special and something they were not expecting. And fans got more from the Hawks during the seventh inning stretch when Patrick Kane, Jonathon Toews, Duncan Keith and Patrick Sharpe all sang.
