Team London Ambassadors - the volunteers who helped make the London 2012 Olympics such a success - staged a flash mob dance in St Pancras station today.
It's the first time the volunteers have returned since the end of the Games - but the Mayor of London is hoping it won't be the last.
Boris Johnson is planning to harness the volunteer manpower in a long-term programme, with initial pilots taking place over the next two weeks.
