When? Where? What?

Even before they enter the bar of the nightclub nightclub in the centre of the city, patrons can hear the music. A regular beat, only slightly muffled, spills out onto the street. Inside the smoky, dimly lit space, women in dresses, tight mini-dresses and teetering heels stand by a stage where nine men play various instruments. Occasionally one woman, known as a 'waitress', although she appears to do little waitressing, breaks into song, usually accompanied by one of the male visitors to the bar. At other points the women sway to the music as customers slip them wads of cash, flashing disco lights illuminating them momentarily in the darkness.
