"Thank 'eavens for leedul girls/ For leedul girls get beeger every day." The Lerner and Loewe musical Gigi is not going to win any awards for political correctness with its story of a girl being groomed for the family business of high-class prostitution. So you could argue that it's wittily defiant of the Open Air Theatre to stage a revival now. This was the first musical I was taken to see at the cinema as a toddler and no one thought it incongruous. How times have changed.
