The BOCOG (Beijing Olympics Organizing Committee) was still mum about the lighting of the cauldron at the Beijing Olympics opening ceremony. But we know Chinese singer Liu Huan and British singer Sarah Brightman will perform the Beijing 2008 theme song at the Bird Nest this Friday night.

The opening ceremony is being supervised by Chinese film director Zhang Yimou and an international team of event planners and advisors.

Zhang Yimou said months ago that his biggest fear was wet weather on Aug. 8, which would force him to cancel some performances in the air or some high-tech and mechanical arrangements due to safety reasons.

“Though contingency plans for bad weather have been prepared, to our delight, latest weather forecasts predict no heavy rains on Friday,” said Zhang Heping. “Thank God bless us.”

To ensure details of the event remain a surprise until the last minute on Aug. 8, design and production teams as well as the cast had to sign a confidentiality agreement before they were allowed to work on the program.

The opening ceremony is due to run from 8 p.m. to 11:30 p.m. local time.
