Duchess of Cambridge and Sir Andy Murray talk tennis

The Duchess of Cambridge surprised schoolchildren at a primary school in south London with a call including former World Number One, Sir Andy Murray. The duchess and the Wimbledon champion released the video to mark what should have been finals weekend at the annual tennis tournament. Sir Andy took questions from the children, revealing he didn't know the scoring system in tennis when he first started playing matches, and confessing the sport was one of the few things he was good at. The school benefits from free tennis sessions from the All England Tennis Club.
