The front of the church is the perfect setting for the Corpus Christi concert. However, it is not the best setting to get good photographs. The main lighting is a large floodlight behind the band. The floodlights at the front are too far away to reach the band.
On the plus side though, the open air setting is OK for getting a sound recording as long as you set the recorder close enough to avoid the crowd noise but not so close that you miss the instruments at the sides.
My photographs are in an album in the sidebar and here is my recording of the music.
