French dance is the same - many of the mazurkas, schottisches and waltzes are played at a steady speed and the dancing is economical and fluid, with the result that bals can go on for hours. Lovely stuff. There's a special extra-toasty circle of hell reserved for people who play schottisches at Irish-tourist-board-advert speed by the way ...
