British pop icon SIR Cliff Richard received a nasty surprise when he sang karaoke recently - the machine wasn't impressed with his performance. The WIRED FOR SOUND hitmaker was in holiday in Oman when he thought he would try a stint of karaoke. But the 66-year old was fuming when he received less than impressive feedback. He seethes, "I visited Oman and at dinner one evening my host set up a karaoke machine. When I sang solo, the machine rated me at 86 per cent. "I really must try to make up that last 14 per cent."
