City of soul: Pop idol Eason Chan features in new versions of the Hong Kong expo theme song.

New music videos presenting English and Putonghua versions of the theme song for Hong Kong's participation in World Expo 2010 Shanghai will be launched on local television channels tomorrow, featuring pop idol Eason Chan.

The music was composed by Eric Suen. Chan Siu-kei wrote the Cantonese and Putonghua lyrics and he, together with Ben Cheong, penned the English lyrics.

The Chinese versions, titled A City with Unlimited Potential, echo the theme of the Hong Kong Pavilion at the expo and pay tribute to the core values and attributes that make Hong Kong Asia's world city.

Titled The City by Your Side, the English version conveys Hong Kong's bright future where people can make dreams come true and achieve a better life.

The Cantonese version launched earlier was sung by Hong Kong expo ambassador Jacky Cheung and Eric Suen, Kay Tse, Hins Cheung, the band Mr and Keeva Mak.
