BEIJING -- An Olympic song has been completed for the 100-day countdown of the Beijing Olympics, said a cultural official of the Beijing organizing committee Tuesday.

The song, Beijing Welcomes You, composed by Hong Kong lyricist Albert Leung, was sung by 100 Chinese top singers from the mainland, Hong Kong, Macao and Taiwan, said Zhao Dongming, director of the cultural activities department of Beijing Organizing Committee of Olympic Games.

"Although each singer has only one sentence of the song, all of them were very enthusiastic towards the Beijing Olympics." Zhao said.

Zhao also said 30 Olympic songs have been solicited from amateur and professional composers after four rounds of contests. But the list will be released on a celebration party on April 30 to mark the 100-day countdown to the Games.

People can download these songs via the Internet and mobile phones, he said.

The Beijing Olympic organizers launched the solicitation campaign in 2003 and gathered more than 70,000 lyrics, over 4,000 songs in four rounds of contests.
