Another very long, very full and very sultry day came to an end with our performance in the Iglesia San Roque in Santa Cruz, the center of the festival.  With the windows and doors closed, the church was mighty hot; we were glad to have opted for wearing shirts rather than jackets.  The performance was packed and the audience was extremely attentive and extremely responsive to the music from the Bolivian and Mexican archives and our encore of two American spirituals - "We shall walk through the Valley/ Good News" and "Chariots coming."   The day started with lunch at the festival headquarters where all the musicians eat when in Santa Cruz, followed by a visit to a crafts market where Adam acquired a flute to play (briefly) in the concert, and we posed in front of the Cathedral.  Fred is accompanyng on a portatif organ of which there are four in Bolivia, tonight's made in France, tomorrow's made in Holland, and the one in San Xavier (of which Father Piotr is very proud) was made in Bolivia.  Tomorrow is announced as an extreme weather change, from hot and muggy to cold and wet.  You'll be the first to know!
