Pop star Whitney Houston will perform in Wan Chai tomorrow night at an exclusive multimillion-dollar party hosted by tycoon Richard Li Tzar-kai. The businessman is spending more than $20 million flying in Houston and a host of other overseas music names for a millennium show at the Convention and Exhibition Centre. The marathon 11-hour event - pulled together only in the past month - is aimed at promoting Mr Li's Cyber-Port development abroad and putting Hong Kong on the global map as an information technology hub. The South China Morning Post understands that about 1,000 guests will drink champagne during a four-course dinner in the centre's grand ballroom, the venue of the 1997 handover ceremony. During the evening, giant video screens will show live digital video coverage of a 20-minute laser and multi-media show being staged at the Cyber-Port site in Pokfulam. Bands Sister Sledge, All-4-One, Canto-pop singer Eason Chan, Taiwanese act Dick and the Cowboy and Beijing group Tang Dynasty will perform throughout the night. After midnight, another 2,000 invited guests will enter the ballroom; Houston will sing for about an hour from 1am and the party will run until 7am. The 'Ultimate Millennium Party - Utopia' has officially been organised by the Hong Kong Cancer Fund, with proceeds from the event going towards a new patient resource centre for the Prince of Wales Hospital. The Cancer Fund has been planning the party for about six years - it booked the ballroom before the Convention and Exhibition Centre was built. But in the past month, Mr Li is understood to have stepped in and booked up to half of the 90 tables - each costing between $60,000 and $100,000 for 12 people. He then hired entertainment co-ordinator and promoter Andrew Bull, who brought Celine Dion to Kai Tak last year, to book and fly in the artists. Pacific Century Cyberworks group managing director Alex Arena said the show was a way of telling the world that Hong Kong was about more than banking and property. Houston last performed in Hong Kong in May 1993, in a one-off concert at the Queen Elizabeth Stadium with her husband, Bobby Brown.
