Green Day will be covering John Lennon‘s “Working Class Hero” on the upcoming album Instant Karma: The Campaign To Save Darfur. All proceeds will go to support Amnesty International’s campaign. The campaign is aimed towards the urgent catastrophe in Darfur, Sudan. “Working Class Hero” was featured on John Lennon/Plastic Ono Band, album in 1970. The song was considered one of the most overtly political songs by the former Beatles, with its themes of class and social alienation. Green Day will also be shooting a music video for the song. Expect the single to be released on the radio and iTunes on April 30th.
