Zombie dear, we should sit down sometime and review how relevant Gilbert remains on the stage. There is no satire in popular entertainment to beat the spectrum of his 'out-of-date' brilliance. Take Utopia, Ltd. for example. It's about a tropical paradise where everyone is equal, and crime and banks are unheard of, and then they fall victim to English bluster about the British superiority as a race, culture and "system", bringing misery and heartache down upon the people. Now, if that's not apt metaphor for what brought about Britex, nothing is
As for culture, if one wants to see a performance of the stage work of Arne, Climenti, Ethel Smyth, Balfe and a host of other British composers, one has to travel overseas. (fortunately for us...you do a good job at keeping Benjamin Britten all to yourself...) It's the same in France, and in America - always the imported seeds gets the careful germination while the native blooms are neglected.
