World peace concert

Bands, ballet dancers, actors and athletes are joining the campaign tonight for a global day of peace.

Razorlight and Eliza Doolittle will headline a concert at London's O2 arena tonight in honour of world Peace Day.

The campaign for a global day of non-violence began more than a decade ago, and since then it's won U.N support as well as the backing of a host of celebs.

They want governments around the world to agree to a day of non-violence in 2012.
