The author of "hard-hitting songs for hard-hit people" – and America's alternative national anthem, This Land Is Your Land [full version: 4min 31sec]. Only recently have Springsteen and Morello decided to play the full version, never included in songbooks, with verses assailing private property. Nora Guthrie believes that these were omitted to simplify the song for schools; Morello that "they censored out all the verses which indicate what a revolutionary, class-war anthem it is".
A great inspiration for the Occupy Movement.
