"Go Cubs Go" by Steve Goodman. Not only do they play it at Wrigley after every Cubs win, but Goodman was a folk singer and a huge Cubs fan who died of cancer in 1984, just a few months before the Cubs won the division and made the post-season for the first time since 1945. The Cubs carry on his legacy by playing Goodman's song and Goodman himself represents every Cubs fans' biggest fear: that you will die before you get to see the Cubs win the World Series.
