Well, isn't this just patriotic.

Thursday night at SXSW, Bruce Springsteen invited the Arcade Fire's Régine Chassagne and Win and Will Butler, Tom Morello, Alejandro Escovedo, the Low Anthem, Eric Burdon of the Animals, and many others onstage to join in on a cover of Woody Guthrie's folk nation anthem "This Land Is Your Land." Watch the video above. Then salute the closest flag.
