Boston 6 Athletics 4

So I am watching the Red Sox/As baseball game tonight and the As score 4 runs in the second inning. Then the Sox come back and score 6 in the third inning. As soon as they score the sixth run the stadium organist starts playing a Chicago tune. I didn't recognise it at first but I was wondering why she would be playing a Chicago tune at that point. Then it hit me. The song was 25 or 6 to 4. Now I know what that song is about, a future baseball game.
