河西智美ら出演「セーラームーン」ショー開幕、5戦士があの曲を披露 - ステージナタリー
Some photos from the show. Looks good, but I'm still not crazy about the fabric choices, and Beryl's dress is a literal weird. (Also, apparently Kyoka had to resign due to ill health, so Beryl will only be played by Makoto Aikawa now.)
There's a "performance part" and a "live part" (whatever that means). Some of the songs performed are "Otome no Policy," "La Soldier," "Tokoyami no Dark Kingdom" (Beryl and Kunzite's duet), "Ichirin no Bara" (Tuxedo Mask's song), and "Watashi-tachi Sailor Guardians".
