Magic piano

I grew up listening to Children's Favourites with Uncle Mac on the radio, and one of my favourites was Sparky's Magic piano that played itself and talked to Sparky. Of course there were others, Nellie the Elephant, The Runaway Train, The Ugly Duckling, Gilly, Gilly, Ossenfeffer, Katzenellenbogen by the Sea, to name but a few. We lived in a cottage that only had gas lamps, so our radiogram was powered by a car battery ! Dad used to get it charged up every week so he could listen to Hancock's Half Hour. The piano in the picture is playing in our local shopping centre... But it doesn't speak....
