Film star Jackie Chan, Andy Lau, Alan Tam and other Hong Kong entertainers will record a pop song to promote the 2008 Beijing Olympics, an assistant to Tam has said.

The song, titled "Olympics Beijing", is separate from the official theme song for the 2008 Games, the assistant said.

She said the Mandarin-language song, written by Eddie Ng, will be aired in China.

It was unclear if the song would be released on CD.

The assistant said Chan has signed on for the project, but hasn't recorded his part yet.

Others who have already completed their portions are Lau, Tam, Hacken Lee, Shirley Kwan, Andy Hui, William So and Jordan Chan, she said.

Other big names in the entertainment industry are involved with the Beijing Olympics, a major source of pride for the Chinese.

Famed Chinese director Zhang Yimou will oversee the design of the opening and closing ceremonies.

American director Steven Spielberg has also signed on as a consultant for the two ceremonies.
