The voice of racing for a generation of Hong Kong fans, commentator and TV personality 'Uncle' Bill Tung Biu, died last night, aged 73. It is understood he had been battling illness for some time. He died in St Paul's Hospital, Causeway Bay. Tung, born in 1933, came from a family steeped in horse training that began with his grandfather and continued with his father, who worked in stables in Hong Kong before the second world war. He learned the arts of both training and riding at a young age. Tung began commentating in 1967 for Rediffusion Television, the former Asia Television. He soon became famous for his outspoken and often critical style, as well as his deep knowledge of horses. He hosted television racing programmes for 30 years until 1997. 'Uncle' then became a trainer in Macau, becoming champion trainer in his first season. The multi-talented Tung was also a screen personality in Hong Kong. He starred in a string of television dramas and Hong Kong movies from 1978 to 1996, including the original Police Story in 1985 with Jackie Chan.
