TOP pop promoter Andrew Bull has taken time off from fixing up a Michael Jackson concert in Hongkong to buy a greyhound in Macau. Bull, a successful Hongkong impresario, is the latest in a lengthening line of leading local figures to get into the booming greyhound business at the Macau Canidrome. ''I have known Andrew for a while and he was quite happy to come in for a dog last weekend. He came out of the barrel in the draw and I am now waiting for him to fax me with a name for it,'' said kennel manager Brian Murphy. The Irish-born Canidrome official is walking around with a smile these days having concluded a good sponsorship deal with the Zung Fu company for a special Cup race at the annual Macau Grand Prix weekend. Zung Fu Motors (Macau) are the agents for Mercedes Benz and Murphy is angling for a Gold Cup race to coincide with the annual motoring extravaganza in the Portuguese-administered enclave. ''We always do excellent business at the Grand Prix weekend and we have been looking for some time to get a good sponsor so that we can put on a really top quality race. ''Mercedes are ideal as they are so obviously associated with quality cars and the Macau Grand Prix. We don't have the details finalised yet but they are in and it will be a most attractive race,'' said Murphy. The Canidrome calendar currently features a major St Patrick's night thrash and a Scottish Night which will be held this year on June 19. And just in case the Canidrome's friends from the southern hemisphere felt they were being left out, there will now be an Australian Night in late September with already two sponsored races guaranteed. The guest of honour at the big event will be the Australian Consul General in Hongkong, Bob Jennings and the Canidrome is confidently expecting a big turnover for the occasion.
