The agency, working with BT and Childline to 'highlight the need to listen to children', launched a competition with BBC kids current affairs show Newsround to find a child to be the voice of the Speaking Clock for a week.
The winner, a 12-year-old Scottish schoolgirl called Alicia, was on a cruise with her parents in the Caribbean when Sinclair Mason received media calls seeking interviews with the youngster.
McKeown says: 'I had to track down the ship and co-ordinate live interviews to the broadcast media from the Bahamas, with Alicia talking to the press from her cabin on a sat-phone'.
