The SATB arrangement is based on this solo version. It is not identical. We do not currently have a demo version of the choral arrangement.
The $25 fee covers your entire choir. You may make as many copies as you need with this license. This is less expensive than the minimum 6 copies you would need at $5 each (director, pianist, 1 soprano, 1 alto, 1 tenor, 1 bass).
