A favorite song of Ed's?

[Jhammes]

Well, this post may be way off topic, if so, please feel free to remove...
still, this sound recording made me think of Ed the guard.

There were so many running gags about Ed remembering Lincoln, the Civil War, etc., surely he knew the popular songs of the day?
