I recently attended a dance weekend where the excellent callers, while teaching dances, used the phrases ".. as in Rory O'More" and ".. as in Petronella"Many of the dancers in attendance probably have never danced either Petronella  or Rory O'MoreThe movements implied by these terms can be easily explainedI've heard callers ask dancers to "Petronella one place."But if the the world can xerox a document, or google for information, no deity would probably object if contra dancers occasionally "petronella." Michael Fuerst      802 N Broadway      Urbana IL 61801      217 239 5844
