The announcement that the group will perform at the ceremony on September 9 has been made ahead of tomorrow’s milestone of 100 days to go until the start of the Paralympic Games.

More than 1million tickets for the Paralympics also go on sale tomorrow at 11am.

The Paralympic Games closing ceremony is called Festival of Flame and will see Coldplay perform a live and one off concert in the Olympic Stadium, broadcast to an estimated worldwide audience of 750m people.

The band has been working with Kim Gavin, artistic director of the Olympic and Paralympic closing ceremonies, and Coldplay’s live show co-designer and Paralympic Games closing ceremony designer, Misty Buckley.

They will play a set of their most iconic music alongside a cast of almost 2,000 performers in the Olympic stadium, providing the soundtrack to a celebration of Britain’s rich culture of festivals.

Chris Martin, Coldplay’s lead singer, said: “Being asked to play at the closing celebrations for the Paralympic athletes in London is such a great honour for us.

“Kim Gavin and Misty Buckley are working hard to put on a spectacular Paralympic Games Closing Ceremony for the athletes and spectators in the stadium, and everyone watching around the world, and we are so happy to be involved.

“It will be one of the biggest nights of our lives and we’re very excited to try to create a performance for the last night of the games that will close London 2012 in style.”

Mr Gavin said: “The closing ceremony of the Paralympic Games is essentially a celebration of the achievements of amazing athletic endeavour of Paralympians from around the world over the previous 11 days.

“What better way to demonstrate our respect and commitment to these athletes than by celebrating with Britain’s most internationally renowned band.

“Working with Coldplay for the closing ceremony will be a great way to close the Paralympic Games and audiences will have the chance to see and hear their music in a totally unique way. Our show will be a celebration of the UK as a centre for festivals, which is a fitting finale to the amazing festival of sport that is the London 2012 Games.”

Tickets going on sale tomorrow include those to the Paralympic Games’ opening and closing ceremonies, and to all sports, including athletics, which has been the biggest seller so far.

Last year’s sale of Paralympic tickets saw more than 1m snapped up by fans.

Seb Coe, chairman of the London Organising Committee of the Olympic and Paralympic Games (LOCOG), said: “The London 2012 Paralympic Games are going to be spectacular.

“I am delighted that Coldplay are going to be helping us celebrate not only the end of a fantastic Paralympic Games, but also the end of a seven year journey.

“With tickets back on sale tomorrow I can guarantee that whatever ticket you decide to go for that Paralympic sport will leave a deep and lasting impression on you.

“The athletes involved in the Paralympic Games are incredible sportsmen and women and I urge everyone to take this chance to be there and to form memories that will last a lifetime.”
