LAB XIV is in the performing part of its program, before those 25 singers go back to their own choral groups for Christmas.  Over the weekend LAB did a return engagement to St. Augustine's in Pleasanton where they now have Fans!, and the Berkeley Public Library where their appearances are very heavily attended.  This morning the visited the Urban School Choir  (directed by Chanticleer alum Brandon Brack) in San Francisco to sing and exchange.  At the end Ben Johns gave a speed lesson about chant notation which the two groups sang together.
