'IF music be the food of love, play on,' wrote Shakespeare in Twelfth Night. And to show what a romantic lot Hong Kong showbiz personalities are, four pop stars got together to highlight the theme of 'love' in a recent concert at the Queen Elizabeth Stadium. Organised by Ultimate 903 of Commercial Radio II and sponsored by Cadbury, the concert attracted hundreds of fans. They were treated not only to the latest hits of their favourite stars - Alex To, Charlie Young, Takeshi Kaneshiro and Tarcy Su - but also offered a rare opportunity to have an insight into the secret love lives of their idols. Fun and laughter rang out all over the stadium as the pop stars shared their views - on everything from romance and courtship to their expectations and fears about marriage - with the audience in a quiz. The highlights of the concert will be aired on radio on Sunday.
