London 2012 volunteers are to take a curtain call with a starring role in the capital's New Year's Day Parade.
There will be 400 Games Makers and performers from the London 2012 opening and closing ceremonies at the central London parade, organisers said.
They join more than 6,000 representatives of London boroughs and guests from around the world in a parade themed "Hats Off To London - Celebration Capital of the World".
Bob Bone, the executive director of London's New Year's Day Parade, said: "London struck gold. The flame may be extinguished but the passion and the warmth still radiate.
"These wonderful volunteers were the outstanding performers of the Olympic Games - not only do they epitomise the spirit of the Games but London itself.
"We wanted to let them take a curtain call on a world stage and show just how welcoming London is."
Pandemonium, a drum crew that performed at the 2012 ceremonies, will be wearing one of their Olympic costumes featuring extraordinary policemen's helmets.
Spokesman Andy Johnston said: "We are terribly excited."
The event will start from mid-Piccadilly before heading through Piccadilly Circus, down Lower Regent Street, to Pall Mall, Cockspur Street, Trafalgar Square, Whitehall and Parliament Square.
