Introduced by Magnus Magnusson. The people in tonight's contest are making a permanent contribution to the world we live in - unpaid and in their spare time.
One day the work of the country's Industrial Archaeologists in recording or preserving the best of the Industrial Revolution must be recognised; meanwhile Chronicle is making its third Annual Award to one of the six finalists in this year's contest for Industrial Archaeology Groups.
They are from Sticklepath, Devon; South Wiltshire; Ryhope, Co Durham; Welsh School of Architecture, Cardiff; Derbyshire; Colne Valley, Yorkshire.
They have come to the studio to watch films of their work and face the questions of the judges Kenneth Hudson, Neil Cossons and Ken Hawley.
The award will be presented by David Attenborough, the BBC's Director of Television Programmes.
