A Little Night Music? No. It's turn-of-the-20th-century Sweden.
Fiddler on the Roof? No. At best, it's a "prequel" to a few characters' lives who begin migration to America at the end of the show. But none of it takes place in America. It's not "about America," the American experience, or Americans at all. It's all prior to that.

American historical themes or events incorporated: Annie Assassins South Pacific

"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
