J is for Jackie Chan
As well as being an official ambassador of the Olympics (and owner of a Segway dealership that will provide a fleet of the upright devices for use at the Games), kung-fu star Chan has also recorded one of the tournament's official songs. 'We Are Ready!' is an unflinching celebration of Beijing's Olympic preparation that stays just this side of sinister, with lyrics such as: 'Waiting day after day/The feelings continue to surge/Building the biggest performing stage/In a bold and generous era.'
