Here is a picture of a brush arbor. It seems to have been the original meeting place of many religious congregations, especially in the South.
We didn't build brush arbors back in my day, in the Catholic Church of the Midwest. It was too cold for outdoor services, so we built gymnasiums. We'd have Sunday Mass amidst the baskets until we got enough money to build a church. Then we'd build a new gym, and move Sunday Mass to the gym when the congregation outgrew the church. This seemed to be an endless cycle. I think that religious services and the smell of old sweat will be forever bound together in my memory.
Psalms 103 and 104 both start out with "Bless the Lord, O my soul," but I think 103 is the more familiar Psalm because 104 is too darn long. I've hear many beautiful renditions of Psalm 103, but I don't think any of them is the one we're supposed to be talking about here.
