It pains me deeply to write about anything related to the Cubs, especially after what they did to the Milwaukee Brewers last week (What the hell happened CC Sabathia and Ben Sheets?), but at least I can relate it to Chicago’s Wilco. The band sang “Take Me Out to the Ball Game” during the seventh inning stretch at Wrigley on Monday, and Jeff Tweedy spent a half-inning in the booth talking about the band’s Lollapalooza performance, growing up a Cardinals fan (Boo! Hiss!), and those ridiculous suits the band wears onstage now.
