Deckchairs provided for early arrivals! Fish and chips and ice cream cones instead of salmon and champagne! Swimsuits (or winter gear, if the weather's bad), but you could always turn up in tux and gown. Stilettos on the shingle!
It's a good idea to choose this opera instead of Don Giovanni and Vivaldi's rare L'Olympiade, because La Périchole isn't something non-opera audiences will have preconceptions about. Besides, in this production by Jeremy Sams, it will be "a hugely fun and bubbly comedy which will be performed in English, is set in the 1940s in Cuba, follows the highs and lows of the heroine Périchole, an impoverished Peruvian street singer."
