Incidentally, the Congregationalists were one of the three sects that merged (the others being the Methodists and the Presbyterians) to form the United Church of Canada, one of the most populous churches in Canada.

In Oz, the church formed by the same union is called "The Uniting Church"; there were several previously existing "United" churches in rural localities where no one protestant brand could muster enough people to warrant a separate building or congregation but, combined, they could. My father's neighbourhood in Sth Gippsland was an example. The Uniting Church in Oz is relatively progressive and liberal.

But I can't (at the moment) think of examples of songs that are endemic to Oz (as distinct from having been transplanted during the recent folk revival) that feature presence or deletion of revenants, daemons etc.
