Chanteylass, you might now find Gilbert & Sullivan's 'The Sorcerer' entertaining, as it owes not a little to L'Elisir d'Amore (as well as a passing reference to Der Freischtutz).

By the way, I see I omitted the name of the Sidney Jones operetta which was one of the inspirations for 'Madama Butterfly' in my last post; it is 'The Geisha', written in 1896. One of the numbers, 'Chin-chin Chinaman' later became a street song. Not often performed now, but lots of good tunes, colour and fun.
