My favorites include:
Soon and very soon, we are going to see the King- Andre Crouch
Lord, help me to hold out- the first notes of this on piano make people holler down here in GA
Swing Low, Sweet Chariot- we start this out with a call and response b4 it gets going.
Come to think of it, one of the old traditional methods was for the song leader to speak a line, then lead the congregation in singing that line. This goes back to the times when a lot of people couldn't read, and the small church didn't have hymnals, but its great for teaching your congregation, and it can be powerful. Oral tradition- its good.
God bless your efforts.
