How do I choose between them?
Yeomen - favourite as an "operatic" piece. I haven't seen
Ivanhoe (though I know one aria and one chorus) or
Haddon Hall, or any of Sullivan's non-comic stage works. So
Yeomen has it. Plus I have a very soft spot for it as it was the one that sparked my interest in opera when I was 12 (I should add that I had seen other G&S by that point, so it wasn't just a matter of
Yeomen having been in the right place at the right time).
My musical favourite is either
Iolanthe or
Ruddigore, but I don't know which.
My favourite on the basis of wit alone is
Patience.
Sorcerer contains many of my favourite numbers, as well as many of my favourite parodies.
It is much easier to name my least favourite:
Pinafore is repetitive, samey, and doesn't have enough for the women to do
I would certainly feel differently if I were a principal soprano: Josephine is absolutely my favourite G&S heroine, on vocal criteria alone. However Elsie Maynard is my favourite G&S heroine dramatically. I think
The Grand Duke would be my least favourite if I hadn't performed in it, which has given me a soft spot for it.
I have seen
Utopia Ltd all of once, but it contains two of my absolute favourite G&S numbers: "Eagle, high in cloudland soaring" and "A tenor, all singers above". The fact that my one experience of it was in a brilliant production - which won "Best in Festival" at the inaugural G&S Festival in Buxton - is probably instrumental in my affection for it.
Best all-rounder -
Pirates, I think...
Sorry, I'm still no clearer than before!
