JP - that is quite a wonderful film. Thanks for posting it. Barry's music is a pleasant change from the usual "rinky dinky piano" often used for silent films.
I can't help but thinking ... all those barges full of coal. The thick, gritty, London fogs were caused by burning all that coal in homes and power plants.
The "Great Fog" of 1952 led to so many illnesses and accidents on the roads, that in 1956 Parliament restricted coal use in urban areas, homes converted to "electric fires", and generating stations gradually moved from coal to oil.
Regardless, that is a wonderful film. Thanks!
