He acquired a reputation as a Chicago sports hanger-on during his embrace of the White Sox during the 2005 World Series. Was that a fair charge? Only in that one isolated incident. (In his defense, he may have had a fever or something).

Anyone who knows John says that he has been, and always will be, a Cubs fan.

When the Huffington Post debuted their Chicago page last year, he pretty much confirmed those suspicions by writing this...

"Wrigley Field and all-things-Cubs, when Jose Cardenal was the only player who could really play. When it was Mick Kelleher and Larry Biittner and George "the Baron" Mitterwald -- and Pete LaCock on first base and "Tarzan" Joe Wallis in centerfield. And Bruce Sutter with that unhittable split-fingered fastball... Ride the El up from Evanston, change on the Howard line and take the train to Wrigley -- which I did as many times as I could scrape together $2.50 for a one-way kamikaze mission, and another $1.75 for bleacher seats, then steal hot dogs and Cokes from the vendors before taking the train home after the game...

Through the '80s, with Gary 'The Sarge' Matthews hitting third, taking us to our first division title in 7 million years. The great Andre Dawson and Sammy Sosa, getting us to the playoffs but never all the way...

From Jack Brickhouse and Billy Williams to Harry Caray, liquored up on a hot summer day, down by seven runs and loaded for bear, most of my childhood was at least partially centered on this Mecca of baseball, this civic shrine that is home to the Chicago Cubs. Every visit to Wrigley Field adds six months back onto one's life expectancy -- doctors have proven this many times."

No Sox fan could or would write that.

He proves it again and again each time he comes to Wrigley to sing "Take Me Out to the Ballgame."

But he really proved it in 2008.

Cusack was booked to make a movie in October, but worked a clause into his contract to allow him to leave to watch the Cubs in the playoffs. "I told the producers, 'I'm going to the Cubs' play-off games so I can't be on the set those dates.' They had two choices: reschedule or I'll be AWOL."
