Who needs new singers when the veterans are going from strength to strength - Sam 'God of Songs' Hui created mania last year when his comeback concerts sold out long before tickets hit the box office. Now it's the turn of another icon, Paula Tsui Siu-fung, whose comeback concert is scheduled for July. Tsui has impeccable credentials as an industry veteran. Late singer Anita Mui Yim-fong entered showbiz performing Tsui's The Wind's Season in a singing competition. Tsui has been a pop diva since the 1970s, when she sang numerous theme tunes for television shows. Emperor Entertainment Group, which is staging Tsui's six concerts, says internal ticket sales were so brisk that it had to start refusing orders before Lunar New Year. CitySeen called the booking hotline several times yesterday and it was just busy, busy, busy. Apple Daily reported yesterday that Tsui says she will lose weight to look her best for the concerts.
