Tom Taylor: Our American Cousin
Lincoln was watching a play "Our American Cousin" by Tom Taylor when he was assassinated.
Ed Jajko notes:
The curious may find a text -- there are variants -- of Our American Cousin at http://onlinebooks.library.upenn.edu/webbin/gutbook/lookup?num=3158, where it has been posted by Project Gutenberg. Another text, rather easier to read, is at http://www.safran-arts.com/42day/history/h4apr/texts/ouramcoz.html. Remember to look behind you halfway through scene 2 of act III.
