Anywhere I can find the sheet music to the musical Metropolis?

I’ve just downloaded the soundtrack to the 80s musical, Metropolis. There are a few songs sung by Judy Kuhn that I would love to learn. I’ve searched high and low for the sheet music. Is it available anywhere? Anyhow I can get the sheet music?
I’ve already tried googling it, and looked through several pages of google and several sheet music websites.
