I went to a David Broza concert, part of a tour he was doing because of the double-CD collection. It was two terrific hours. People I know went to some performances in different venues where he played a similar set-list, but by no means rigid. He always adds something fresh, something new. Have several live recordings, DVDs, etc, you are never disappointed. A set list should be like public speaking, have it written down, but don't be slavish.
