Did you hear Melvyn Bragg’s In our Time on Thursday? If not do catch it on the Podcast it was about Booth and his maps and more; well worth the time. Also Andrew Marr’s Start the Week on Monday a rather more haphazard programme around three books but it does shine a light on London and its cosmopolitan populace again available as a podcast. A health warning on both as they are short and necessarily cursorary but they all add to the rich picture that is the product of London’s history.
