Green Day have released a single. Today. Yes, you read that a-right. A single, today. The band have made their cover of John Lennon's 'Working Class Hero' available to download via iTunes as part of the promotion for Amnesty International's previously reported Lennon covers album 'Instant Karma: The Campaign To Save Darfur'. It's not the first promo, of course - REM's cover of '#9 Dream' was released back in March, whilst Corinne Bailey Rae's cover of 'I'm Losing You' was out in April. Other artists appearing on the record, out 25 May, include Aerosmith, Christina Aguilera, Jack Johnson and Black Eyed Peas.
Publishing royalties for the tracks have been donated to the campaign by Lennon's widow, Yoko Ono, who says: "It's wonderful that, through this campaign, music which is so familiar to many people of my era will now be embraced by a whole new generation. John's music set out to inspire change and, in standing up for human rights, we really can make the world a better place".
