Hello, Ragazzi! (Random Thoughts while Listening to Puccini)

I wonder if Japanese people find Madama Butterfly slightly embarrassing and annoying with its fake Japonaiserie. I wonder this because I found it odd, while listening to La Fanciulla del West, to hear the chorus singing, "Hello, ragazzi," "Whisky per tutti," and other cowboy-like phrases. (Not to mention, "doo dah, doo dah day," which, as far as I know, is not actually from the old west!) 

Whisky Milk Punch at The Bite House.

Come to think of it, Madama Butterfly also has fake American-nesses: that Star-Spangled Banner quote and Pinkerton's inquiry, "Milk punch o' whisky?" to name two.

What exactly is milk punch? I just read a suggestion that there's a comma missing; apparently it was supposed to be, "Milk, punch, or whisky?" On the other hand, there are recipes for milk punch. (Which came first: the drink or the opera?) 

Or, maybe they meant “milk punch with whisky.” (Yes, my mind does wander.)

I also noticed that Puccini has stolen some melodic bits from Phantom of the Opera for La Fanciulla. I wonder if Sir Andrew is aware of this...
