HE'S cool, he is poised, he has presence - and he plays a mean saxophone. No, no, not Bill Clinton. We're talking 10-year-old Dean Charisse, the Antipodean prodigy who is currently gigging at Quo Quo and wowing 'em something ecstatic. And none more so than Bonnie Gokson who, as we all know by now, 'discovered' young Dean busking near the Sydney Opera House. When Keeping Posted joined a small dinner party given at the restaurant by Australian Consul-General Dr Jocelyn Chey, we spotted Bonnie fussing protectively over the young entertainer like a mother hen. Why, at one stage she even whispered to us: 'He's so cute, I want to adopt him.' Another person who was caught up in the excitement of it all was Dr Chey who tapped the table to the beat of Dean's rhythm enthusiastically throughout the meal - her nationalistic pride written large across her face. As Dean launched into Summertime and the languid dirge filled the room, Dr Chey could contain herself no longer. She grabbed the hand of casino tycoon Stanley Ho, one of her dinner guests, and led him on to the dance floor for a measured twirl.
