Famous quotes containing the word twist:

    When we were at school we were taught to sing the songs of the Europeans. How many of us were taught the songs of the Wanyamwezi or of the Wahehe? Many of us have learnt to dance the rumba, or the cha cha, to rock and roll and to twist and even to dance the waltz and foxtrot. But how many of us can dance, or have even heard of the gombe sugu, the mangala, nyang’umumi, kiduo, or lele mama?
