Chanticleer in Sonoma opened its doors today to 69 adult choral singers from all over the country, some who've come every time we've done it biannually for over l0 years, and some new.  We're delighted to see them all.  We gathered at the Green Center at Sonoma State University and got right into Mozart and Mendelssohn with Fred, Kory, and Ben Johns conducting.  Lots more fun to be had between now and Sunday.
