Here in the Land of Oz, the term 'sea change' has acquired enhanced currency in the last few years thanks to the eponymous soapie screened on the ABC (that's the Australian Broadcasting Corporation, in this antipodean context). As with Ariel's chanty, there was a bit of a jeu de mot in the title, the set-up being a magistrate and her family who move from the big smoke to a small (seaside) town peopled with small seaside eccentrics - never to be the same again. Sort of The Ghost and Mrs Muir meets Ali McBeal. Without the ghost (or the skeleton).
