UNICEF Launches New Version of 'Imagine' [VIDEO]

Katy Perry, Shakira and Idris Elba are among many stars who sing in a new version of John Lennon's Imagine, released in association with Unicef. Although I don't see this becoming the next 'We are the world' I'm sure it sends the message. The global charity's version of Imagine has been recorded to highlight the 28 million children across the world who have been forced to leave their homes due to conflict.
