How many churches would allow someone like this brother to sing so freely in a worship service? The singing is really bad, and it gets worse and worse. It is also hard not to laugh. But it is a joy to watch it. The organist tries to follow him, he does not know the lyrics, but the church sing with him and the end a brother keeps saying Amen! What is it that makes a perfect praise? I think we can catch a glimpse of it by having people sing freely to God with whatever they have.
