Olympic Opening Ceremony teaser is revealed

A teaser video has been released of the Olympic Games Opening Ceremony, as excitement reaches a fever pitch ahead of tonight’s three hour extravaganza.

The short clip reveals groups in colourful stage outfits dancing to Tiger Feet by 1970s rock group Mud and cyclists with wings pedalling along to Come Together by the Beatles.

However, the identity of the final torchbearer - the person who will light the cauldron in the Olympic Stadium - is still a mystery.

One billion people are expected to tune into the 'quirky celebration of British culture' at 21:00 BST, which has been created by renowned British film-maker Danny Boyle - of Slumdog Millionaire and Trainspotting fame.

With a total cost of around £27m, the event will feature a cast of 10,000 volunteers, 15,000 square metres of staging, 12,956 props and a million-watt PA system using more than 500 speakers.

As well as a global audience, the Ceremony will be watched in the Stadium by a crowd of about 80,000, including the Queen.

This morning, a mass bell-ringing took place for three minutes from 08:12 BST to build up to the event. Big Ben chimed 40 times - the first time since the funeral of King George VI that the famous bell had rung non-stop for three minutes.

Boris Johnson, Mayor of London, commented: "Let's put our best foot forward, we're an amazing country with fantastic things to offer. This is a great moment for us, let's seize it."
