MUNICIPAL councils should co-ordinate their programmes on overseas cultural groups' performances to ensure better value for money, members say. The Urban Council spent $5 million on the Vienna Philharmonic, which gave only two performances last month, Urban Councillor Ada Wong Ying-kai revealed. More than $4 million was spent on the Boston Symphony Orchestra which gave three performances last December. Figures provided by the Urban Services Department said $22 million had been spent in the 1994-95 financial year on 54 overseas arts groups. They gave a total of 89 performances. Ms Wong said the total budget for cultural presentations last year was about $40 million and overseas groups had used up 55 per cent. Apart from performance fees, the two councils also paid for air tickets and hotels. Ms Wong, who is heading an Urban Council sub-committee to draw up a five-year plan on arts development, said it was time to review the ratio of spending on local and overseas groups. 'We need overseas groups to perform here. Otherwise it is difficult to see how well local groups are doing,' she said. But there was no point in the Urban Council always being the sole promoter. She believed one option was to find sponsors for the programmes. Another option was to co-operate with Regional Council. At present, the two councils operate separately. Chairman of the Regional Council's Recreation and Culture Select Committee, Tony Kan Chung-nin, agreed the councils could co-operate more. They worked together on flower shows and there was no reason this could not be extended to cultural performances. A Regional Services Department spokesman said $11.8 million had been spent in 1994-95 on 68 overseas performances.
