Propped against the railings of a children's playground, in the dappled shade of a huge London plane tree on Camberwell Green in south London, there is a battered old piano. It is one of 30 placed around the capital by the artist Luke Jerram in an installation called Play Me I'm Yours, which was designed to get strangers in towns and cities to actually stop and talk to each other. And it works. Last year, Jerram placed pianos around Birmingham and estimated that 140,000 people gathered around them to either play or listen; he has also done it in Sao Paulo and Sydney.
