The Cubs sit atop the NL Central with just over a week left in MLB's regular season.  That's cause for celebration for one of the team's highest profile fans, Eddie Vedder.  The Pearl Jam lead singer took to the sidewalk outside Wrigley Field to join a couple of street musicians on a version of his band's song Courduroy Friday (9/15) and was at it again on Sunday, that tim sitting in on drums.
