It strikes me as odd though, that "Battle Hymn Of The Republic" could be dropped on the grounds that it moves the show out of the Civil War, yet to have Lincoln recite the Gettysburg Address if anything puts it *more* back in it, than "Battle Hymn" ever did. The Address is a speech that is totally meant for the time it took place in, and it does not have the kind of timelessness the original Lincoln speech did (the less said about the 93 one, the better).
Then again, if I just had the reassurance that the people responsible for the 93 show (specifically Eric Foner, who is to put it bluntly a Marxist historian) weren't responsible for the content of this program, I'd probably view it with a lot less trepidation over all.
