The young ladies and gentlemen (and catering staff) of the Royal Grammar School, Worcester, demonstrate the latest dance 'craze' sweeping the nation's youth. Apparently, since the England cricket side popularised The Sprinkler, the Watusi and the Hully-Gully do not 'cut it' and are no longer 'where it's at'.
(The school wasn't always the home of gilded youth. An ancient foundation, it was IIRC a state-funded grammar school until the early 1970s, when Worcestershire went comprehensive and Bromsgrove County High School became North Bromsgrove High School. RGS, independent though state-funded, picked up their ball and went private.)
