Daughter 1, aged 8, reports that the 4 year olds wanted to do the Wizard of Oz for school. They phone the performing rights people, she says, who refuse on the basis that it would be too close to the centre of London. Quote "Honestly Dad, some people are idiots. Who really thinks that people in London would not go to a play in order to come and see some infants at a School doing it instead". So now the kids are doing The Ozzard of Wiz.
Good thing her Dad was on the Competition Commission for eight years. The gal understands market definition.
