Keyboard: Choir Chants

[HitHardDrums55]

I have been addicted to this sound at the beginning of songs/shows that some bands do, and i've realized that on my keyboard and my friend zac's keyboard we can do choir sounds...i dont really know how to describe it, but it's kind of like singing "AHHH" in different notes...

can somebody write the notes out for either the choir singing in the beginning of the Sister Of Mercy song This Corrision, or if anybody here has the Alkaline Trio Halloween At The Metro DVD, the beginning of that show. they're very similar sounding, but a few different notes.
