Coldplay are set to make a special appearance at an upcoming concert in aid of Kid's Company.

Coldplay are back. After taking time off to focus on new material, the British giants dropped their - rather bizarrely titled - new album 'Mylo Xyloto' earlier this year.

Looking forward to a short December tour, the band have been rushed off their feet. Fresh from a whistle stop tour of the United States, Coldplay entered the usual whirlwind of promotional appearances.

However the band have found time to do their bit for charity. With Christmas fast approaching, children's organisation Kid's Company are rapidly attempting to organise their annual concert in the O2 Arena.

Part supporters of the charity, Coldplay have agreed to take part. Due to play a short headline set, the stadium giants will be joined by a host of other acts for the one off event, titled Under 1 Roof, on December 10th.

More than 20,000 fans will be in attendance with Coldplay set to appear alongside Tinie Tempah and Emilie Sande, with Rob Brydon and Steve Coogan (in his Alan Partridge guise) also set to appear.

Tickets are on sale now.

Looking ahead, Coldplay will play a short burst of - long since sold out - British shows in December. When 2012 rolls round, the band will prepare for a much lengthier tour containing some enormous venues.

Forced to expand the tour due to overwhelming demand, the 2012 leg contains a grand total of three nights at the Emirates Stadium.

Coldplay's full tour schedule is as follows:

3 Glasgow SECC (SOLD OUT)
4 Manchester MEN Arena (SOLD OUT)
9 London O2 Arena (SOLD OUT)
