Befuddled mainlanders confused by Hong Kong's mod cons and strange non-spitty manners have a lifeline this Lunar New Year. Good Mood AM 1044 radio show host Sylvia Lau has organised a concert to help them make sense of the city's history and lifestyle. The event, Singing With A Passion For Hong Kong, will feature popular songs from the 1960s plus films and slide shows. The concert is an extension of Lau's weekly radio for ex-mainlanders. The February 8 concert is at the Cultural Centre in Tsim Sha Tsui.
