Wisconsin’s sweetheart, Justin Vernon aka Bon Iver, went on Jimmy Fallon in advance of the release of his second album. Instead of performing a number from that album, Bon Iver, Vernon hands clenched and eyes at slits, sang Bonnie Raitt’s tearjerker, “I Can’t Make You Love Me” accompanied only by piano. Bon Iver is due June 21st, but it appears someone at iTunes was pretty eager to get it into the world.
