Why are Gilbert & Sullivan so popular?
The answer to this question may depend on where you are. Here in the Netherlands, I think Gilbert and Sullivan were virtually unknown until Topsy-turvy came out. Over here Viennese operettas have always had a devoted following among people over 50, though they’re considered naff by everyone else. Strauss’ “Der Fledermaus” and Offenbach’s light operas are part of the “opera mainstream” and are regularly performed.
