At one of the 2006 pub sings someone, and I still don't know where
the female voice was coming from, started 'Down to the River To Pray' in
the manner that it made its appearance in the film "O Brother Where
Art Thou?'

The result was amazing, and sounded for all the world as it did in
the flick--- just as haunting as the harmonies fell in place and
built in layers.

To complete the authenticity, someone in his cups must have been
quite moved, as he managed to 'baptize' himself in the pond
across from the Visitor Reception Center when the session broke
up. Speculation, however, is that he was moved more by 'spirits'
than by 'The Spirit.' That, and gravity.
