I love G&S and am not so quick to diss Sullivan as a Composer as seems to be the fashion these days. True he's no Wagner or Verdi but...
For a start he worked up the tunes after the words were written, and his crusty partner was a stickler that the words should all be audible. They weren't trying to break the boundaries of the art, more often parodying the existing forms.
Just imagine being presented with this written down on paper and having to find a tune to sit under (thanks Julie Styne) these words.
(There was a fine film made by these players but sadly it's not avaible on Youtube.)
I love the musical pastiches they carried out and I also believe that there are places where his music is truly memorable and affecting. A quick search found this - ignore the visuals they are hackneyed and distracting.
Also please reflect on how we tend to undervalue 'Comic' in the performing arts. Think of the films you've most enjoyed and are personal favourites and I bet a good no are comedies. Then make a list of the 'best' films or plays you've seen and I bet you go for the serious stuff. Next reflect on how many dramas turn out fine and also how many comedies fall flat. Comics know, just ask Pagliachi, it's not easy to produce delightful light entertainment. Gilbert and Sullivan left us with treasures and their influence on the musical theatre is unparalleled.
A minor composer perhaps, but one I'm delighted to know.
Can't resist adding
Man goes to doctor. Says he's depressed. Says life seems harsh and cruel. Says he feels all alone in a threatening world where what lies ahead is vague and uncertain.
Doctor replies, "Treatment is simple. The great clown Pagliacci is in town tonight. Go and see him. That should pick you up."
Man bursts into tears. "But doctor...I am Pagliacci."
