"Every Touching Moment," the theme song of the Singapore Pavilion at the 2010 World Expo, has been released in Singapore, Malaysia, the Chinese mainland, Taiwan and Hong Kong, the "Beijing News" reports.

Four Singaporean pop stars, including Stephanie Sun, JJ Lin, Tanya Chua and A-do, contributed vocals to the song.

A music video of the pavilion's theme song will be released officially on April 19 and is expected to be a hit with visitors to the Singapore Pavilion. The four stars will be in Shanghai on that day to attend the event.

The song, which was written in Chinese by Singaporean singer and songwriter JJ Lin, aims to create touching moments through its description of the relationship between cities and mankind. It is one of the highlights of the Singapore Pavilion.

In line with the World Expo theme "Better City, Better Life," event organizers came up with the theme of a musical journey known as Urban Symphony.

"With Urban Symphony, we hope to bring 'alive' the inspirations and the aspirations of Singapore as a city, as a people, as a culture for the Chinese audience, as well as for the international audience and show to them the progression we've made in urban development and programming," said Ken Low, Assistant Chief Executive of the marketing group at the Singapore Tourism Board.
