If you are looking for sheet music for your church organist then you may want to consider trying a new type of music that you do not always get to hear.
While the classical church music is very pretty you might want to try a new style of music that will get your parishioners into the services. Many people decide that they want to go to church to hear the music, it is very much a part of how they worship and praise their Lord.
If you would like more people to get involved in the music of the church then you should include some classical music that will appease more parishioners. Jesu Joy of Man's Desiring is a prime example of this kind of classical music. You will hear great feed back from your parishioners after they hear the music and the way that it accompanies the words and feel of the song.
