Arcade Fire's "Rococo"

I just listened to Arcade Fire's The Suburbs.  I'd never noticed that there's harpsichord in "Rococo" (or at least I hadn't paid much attention to it), but it's fitting.  I don't know much about it, but Rococo was an artistic period in the 18th century, sort of a smaller branch of the Baroque, if I understand correctly from my skimming of the Wikipedia article.  And the harpsichord was "widely used" in Baroque music.
