The nuns in The Sound of Music had to solve a problem like Maria. For the producers of the musical which opened at the Academy for Performing Arts this week - she was the least of their worries. Thanks to a little bird in Melbourne and a drugs bust at Kai Tak, the opening night of the $15.6 million stage show - starring 70s pop star Marie Osmond - almost didn't happen. With less than 12 hours to curtain up at Wednesday night's gala premiere, the musical's set was Von Trapp-ed in Bangkok after a bird flew into the engine of a jumbo jet chartered to ferry it to Hong Kong, delaying the flight overnight in Australia. The plane's landing slot at Kai Tak was lost and the next available one was at 10 am on the day of the first night. But there was worse to come. As panicking producers readied an extra 110 stage hands to put the set together, Customs and Excise drug investigators impounded the whole plane load as part of a search of all flights from Thailand. Producer Dale Rennie said: 'It was pouring rain and the set was soaked. Not only was it late but it needed repainting. It finally arrived at the theatre at 1.15 pm, less than seven hours before the show started'. As a blissfully unaware first-night audience - including Financial Secretary Sir Donald Tsang Yam-kuen and Sir Run Run Shaw - sipped cocktails, an army of stage hands were still hard at it. And even when the curtain finally went up 35 minutes late, the hills weren't so much alive with the Sound of Music but the banging of hammers and the frantic swish of paint brushes.
