I’ve been working on this project for almost a year, so I’m very excited to finally be able to release it! An index of song translations is below, as well as (as of Feb. 2018) the new text script; the script is matched to the 2010 Moon Troupe Senshuuraku performance, but should largely work with any filmed version of the 2008 or 2010 productions. The 2017 production had some larger changes and a new song.

This list only includes the songs substantial enough to get their own posts: there are a lot of brief reprises that were not included (a couple relevant ones are).
Song Translations:
A Piece of Courage, Storybook, Madame Guillotine, You Are My Home, Prayer, Into the Fire, Falcon in the Dive, Who Is The Scarlet Pimpernel? When I Look at You, You Are My Home (reprise), Where’s the Girl, The Creation of Man, I’ll Forget You, The Riddle, We Seek Him Here, Bonds of Love/Ai no Kizuna, Madame Guillotine (reprise), She Was There, Days of Glory/Eikou no Hibi.

New song from 2017: Robespierre's Frustration (New Age of Man)

Note that while the script apart from adlibs is essentially the same between 2008 and 2010, the names of all the members of the League were shuffled around between productions for unknown reasons, and this seems to have happened again in 2017.
