Until then, I found this adorable production in Japanese and a fan-made English dub.
First, the original Japanese
And the fan-made English version.
The girl who wrote the lyrics to the English version pointed me towards the instrumentals and the english lyrics she wrote and I'm working on doing my own version of this 10 minute musical. I am very excited as this vision of Wonderland is very close to what I had in mind in my book.
I can't wait.
