In 1977, Tony Palmer was asked by ITV to document a burgeoning and exciting scene happening amongst Lancashire's youth for their weekly news magazine series, This England.
He brought TV cameras in to Wigan Casino, not imagining what he would find there. He saw scores of teenagers arriving when most pubs would be closing, all there for one purpose - dancing all night.
Lights had to be brought in, much to the disdain of the organisers, to illuminate the normally darkened dancehall so that the cameras could film the crowds.
However, the footage captured has now gone on to be the 'go-to' film whenever any documentary needs authentic 'Northern Soul' scenes.
