CHIEF Secretary Sir David Ford was the smash hit of a celebrity tennis challenge at Victoria Park yesterday, unleashing a blistering volley that hit his opponent, sports commentator Chan Yiu-mo, right on the nose. He was one of 36 celebrities who served up the charity fun. But the chairman of the Hongkong Tennis Foundation did not fare very well - Sir David and his movie star partner Melvin Wong were awarded the wooden spoon in the cup division. Among the showbiz stars was pop singer Alan Tam, who has spent the last week in a very different sort of court - he is embroiled in a High Court battle over the use of his name and face on a karaoke laser disc cover. Macau casino tycoon Stanley Ho, Jardine's taipan Mr Nigel Rich, actress Olivia Cheng and film star Nat Chan Pak-cheung were among those who helped raise $800,000 for the development of junior tennis in Hongkong and $100,000 for the Community Chest.
