On the stage, nine handsome black guys, in their thirties, in dirty blue working trousers, bandanas round their foreheads and waists, and black rubber boots –of course!– on their feet, swept an enthusiastic public along with their dancing...
   And, very soon, under the fabulous sound of the rubber boots (South African ? In any case, we do not know them here !), the audience, carried away by the dancing, were unable to resist clapping their hands. Very soon also, their feet were stamping... The atmosphere rose to a climax and stayed there for the 75 minutes of the show.
