The band also performed the song live at Children in Need 2008 on the BBC on 14 November 2008 , before donating £ 250,000 to the charity . Take That performed " Greatest Day " at the 2009 Brit Awards . They performed the song live whilst upon a UFO stage prop but as the prop descended into the audience they were claimed to have lip synced . It was revealed after in Take That/Take Two that the technical people said they could not sing live as they were on the UFO stage prop . This was because of where they were positioned , which was right in front of the speakers , and if they had then the mics would have fed back
