I saw Assassins many years ago now. It's a captivating, eerie show that gave me chills. Sadly, since it's a highly charged topic about a quarter of the audience walked out from the production I saw.

I'd gone with a bunch of people from the choir I was in and everyone was humming "Everybody's got the right to be happy" the next day. Who says Sondheim isn't hummable? ;-)
