Your wife sounds like a classy lady.
I've taken my wife to see Wicked on Broadway several years ago (I've seen it three times), but Hamilton has never been an option due to impossible to find tickets, outrageous prices, having a five year old son, and my work schedule. I was super excited when they announced the nationwide tour, but we're moving to California in a few weeks and don't have any viable options. I was also super excited when they announced they are filming it, but all the discussion on that front makes it sound like it won't be released for quite some time. It's pulling in truckloads of money, and that would probably hurt some of that momentum. Too bad.
I'll stick with listening to the soundtrack, and will read the book this summer.
