Two years ago, Harry Malkin was working down the pit. Now his magnificent charcoal sketches of life underground have been exhibited at the Royal Festival Hall in London. This was made possible by the work of the Yorkshire Art Circus which wants to take the snobbery out of art and give local people a voice in recording their own history. Ringmaster Ian Clayton. a local writer, takes a grand tour of the Circus to see the work of ordinary people who are not simply 'on Earth to make the numbers up'.
