Veteran singer Paula Tsui Siu-fung couldn't shelter her fans from the rain, but at least she thanked them for queuing in a downpour yesterday. They were out in force, snapping up tickets to her just-extended comeback concert series that starts next month. 'I have to thank my fans for queuing up under such terrible weather,' she said. 'I'm under a lot of pressure ... please don't expect too much, but I promise I will do my best.' Her die-hard fans queued in a thunderstorm at the Urbtix box office at the nearby Hong Kong Cultural Centre in Tsim Sha Tsui. Meanwhile, Tsui was speaking at a press conference at the InterContinental Hotel in Tsim Sha Tsui - her first public appearance since she announced the concert series in February. She announced five extra dates for her first concerts in 10 years. Tsui will now perform 20 shows between July 23 and August 11 at the Hong Kong Coliseum. Bedecked in colourful jewellery, Tsui promised to wear her trademark dalmatian-spotted outfit at her concerts. 'This time it will be even more flamboyant,' she said. The deep-voiced singer, whose career began in the 1970s, has been dubbed the female equivalent of so-called 'God of Song' Sam Hui Koon-kit. Tsui has performed in more than 150 concerts since her solo debut in 1983. Tickets to the initial eight shows in her comeback series were snapped up in just one day. Another seven dates were added but tickets also went quickly. Tickets for the additional five shows went on sale yesterday. The enthusiastic response to Hui's comeback performances last year boosted organisers' confidence in putting on shows for a more mature audience, said Ng Yu, chief executive officer of the Emperor Entertainment Group, one of the concert organisers. 'For this type of concert, you hardly need to do any promotion. [Hui and Tsui] are the best of the best. They haven't performed for so long, and people miss them,' he said. 'Usually the audience is a bunch of high-powered consumers in their middle age. Money isn't really their concern.'
