Radio Seagull on air: Jon Rogers           Mr Rogers lives in a cave on the sunshine island of Tenerife, having escaped there following a long running battle with life in the cold and damp.   Sadly, whilst one might expect him to be a tanned shade of brown, Mr Rogers remains snowy white since he spends much of his time underground in his studio.   Mr Rogers plans to take a course in architecture soon, which will hopefully teach him that if he ever moves his studio it will be to somewhere that at least has a window!
