Suez was a difficult situation for the left as a whole to come to terms with politically, but even here it is trad jazz that accompanies the political marchers.
Most of the 10,000 marchers were indigenous.
When the police regrouped to form a stronger cordon, the marchers responded with a sit-down protest before voting to disperse and meet again at city hall.
The routes began at accessible assembly points and ended at sizeable plazas or open spaces appropriate for closing ceremonies and the dispersal of marchers.
Bands would play on pavements as the marchers approached and went by, and then they would get moved along by the wagon periodically.
The harsh regional minister had the marchers gassed and many arrested.
Toward the end of the track, a conflict between marchers and a policeman is enacted musically through a barrage of vocal samples.
All the marchers carry on their backs a tag with this most important number on it.
