Razorlight have joined the line up for the Peace One Day concert at London's The O2.
The 'Golden Touch' rockers will appear alongside acts including Newton Faulkner, Yusuf (Cat Stevens), Eliza Doolittle, Youssou N'Dour, Flawless and the English National Ballet at the show on September 21.
The O2 concert is the biggest event yet for Gilley's Peace One Day campaign, which in 2001 led a process that resulted in the unanimous adoption by UN member states of the first ever annual day of global ceasefire and non violence.
Jeremy Gilley said: "Peace One Day is calling for and working towards a Global Truce on Peace Day 2012. We have a clear strategy and we hope this will be the largest reduction in global violence in recorded history, both domestically and internationally. This day is as much about non-violence in our schools, our homes, workplace and local communities as it is about ceasefire on the international stage.
"Everyone has a role to play. The O2 show launches a 365-day countdown to the Global Truce. I'm honoured to welcome Razorlight and so grateful to all the artists for giving their time to help Peace One Day take this message to the people of the world."
