Hello, sian! And Happy New Year to you too.

I'm glad that this conversion will include comments about non-Black church processionals.

I confess [no pun intended] that I only know about the processionals in Black American Baptist churches. But choir processionals may also tradionally occur in AME, AMEZ, and COGIC churches {African Methodist Episcopal; African Methodist Episcopal Zion; and Church of God In Christ}. And they may also be done in Black churches of other demoninations.

I intend to search for online articles about Black church services, in general, as well as for online articles about Black and non-Black choir processionals. If I find such articles, I'll post their links in this thread.
