This is a song for Palm Sunday by John Angotti that has an easy refrain for the assembly and a set of challenging verses for a soloist. The assembly can keep singing their part under each verse as well.
The sheet music is available for purchase at WLP where the text is in their sample.
In my funk style backing, I have just put one melody line to reduce confusion, but you can sing the refrain under the verses. The sheet music says 80 bpm but 100 works better.
