...and it definitely isn't the gorgeous Walpurgisnight - scene which was added to the beginning of the last act in 1869, where Mephistopheles shows Faust the folk celebration before May Day (still top traditional night to celebrate and dance here), when the souls of the dead are released briefly to wander as they will. George Balanchine did the best job on this one...

it says, "Lincoln enjoyed many operas, including Gounod’s ‘Faust,’ whose famous ‘Soldiers’ Chorus’ was a special favorite."

Here is the Soldiers Chorus on YouTube:
