Rage Against the Machine guitarist Tom Morello donned his folk ater ego the Nightwatchman Thursday to support the Occupy Wall Street protesters in Manhattan.  The guitarist addressed the group of protestors, whom he called "friends," before breaking into a four-song set to entertain the gathering.  Morello performed three songs from his Nightwatchman catalog, plus a cover of Woody Guthrie's classic folk standard, "This Land Is Our Land."
