Finding music from "Yo-Yo Ma plays Ennio Morricone"

Hello!
I'm a fellow cellist who has been searching for sheet music from the "Yo-Yo Ma plays Ennio Morricone" album, particularly the music from The Mission, Cinema Paradiso and "Playing Love" from The Legend of 1900.
I'm hoping to find a cello and piano arrangement to perform in an upcoming benefit concert.
If anyone has some information as to how to obtain the music, please do share!
Thank you.

Sue
