Singing the seventh inning stretch at a Cubs game is no easy feat. Just ask Eddie Vedder… or Ozzy… or, umm, Mike Ditka. But those Arcade Fire kids know a thing or two about performing in front of thousands of people, so it’s no surprise that the band’s Will Butler and Marika Anthony-Shaw were up to the challenge when they dropped their own rendition earlier today. Unfortunately, Win couldn’t make it — he was playing basketball or something.
