Woman on Radio 4 tonight talking earnestly about how difficult she found it responding to a visit to the North Pole on an ice breaking ship ... through the medium of dance. "I can't imagine even indigenous peoples being able to dance at the North Pole, encumbered by all those heavy clothes". Quite so my dear, I imagine they find more time for a little pen and ink cartouches, or some challenging mixed media work involving snow and ... um... ice.
