For the orchestral parts, contact Joe Wolfe. I'll send them but, because I don't think that music should be free, I'll ask you to make a small donation to this medical charity that does remarkable work in the third world: The Fred Hollows Foundation.
About the composer. Joe Wolfe started writing music in the seventies and has since written sporadically for jazz and fusion groups, including incidental music for plays and films. He has written several other orchestral works, beginning with "The Stairway Suite" (a set of orchestral variations on the pop song "Stairway to Heaven" in the styles of Schubert, Holst, Glen Miller, Mahler, Bizet and Beethoven) to his most recent work, "Circle of Fourths", a 5 minute work for orchestra that uses the circle as a chord and as a melodic nucleus. Scores and orchestral parts are available of most of these.
