Interesting for the Fanastasias among us to see this. The new song is performed about 45 seconds into the video; there are also performances of 'The Neva Flows' and 'Journey To The Past'.https://www.youtube.com/watch?v=sivS-ITgoeUI can't understand the lyrics with my mediocre schoolkid Japanese, but some of the music echoes a section of 'Meant To Be'. Based on that, and the song's title, I'm guessing that it's sung during, or close to, the ballet foyer scene? According to https://kageki.hankyu.co.jp/english/revue/2020/anastasia/index_takarazuka.html, the original creative team, Stephen Flaherty and Lynn Ahrens, wrote the song. I believe this is done from time to time for Takarazuka productions.
She Walks In was a song that was written for the show and then cut and replaced with Everything to Win. Derek Klena has talked about it in a few interviews here and there about how he loved the song and then it got cut very early on in the process.
At this point...I would love to see ANY live production. I had tickets to the cancelled tour this year. I prepurchased the cast cd as a "souvenir" for the show as I do every show I attend. Yet....no show. Hoping down the road, a tour will be announced. Maybe 2021 or 2022?
