At the height of the industrial revolution in the last decades of the 19th century there was a dance, now rarely seen, that resounded through the collieries and pit villages of the north east of England - the clog dance.

For conductor and musician Charles Hazlewood, clog dance has become an obsession and he plans to put it firmly back on the map by staging a mass flashmob clog dance.

Helped by a team of local enthusiasts led by expert clog dancer Laura Connolly, Charles recruits and trains 140 men and women from across the north east, and one sunny Saturday in a busy square in central Newcastle they ambush the public with a six-minute performance.

Along the way, Charles delves into the history of this fascinating folk dance, learns and performs a few steps himself, and meets and works with some of the key characters keeping this ancient dance alive
