1. music 2.witches in Galicia, 3. pre christian pilgrimage?

[Maura Santangelo]

1. Does anyone know whether there is any music, type or period, that is
associated with the camino?

2.  While checking an Italian site I came across a reference to the
witches of Galicia.  Does anyone know anything about them?
3.  is there a history of the pilgrimage in the same place in
pre-christian eras?

Thanks for any information
