My DVD did not co-operate, so I went out to my PBS Passport and it happily told me -this episode not currently available.-
So, through Serendipity, I ended up watching the episode about the assassination of President Garfield. Really, almost everything I knew about him (which wasn't much) I knew because of the musical Assassins!
OMG, what an incredible documentary. I have seldom been so fascinated and so horrified at the same time.
