The day before our concert we spent time with  our presenter Jeunesse Musicale's youth chorus who were very good.  After a quick dinner near the Konzerthaus we joined about 75 musical Viennese citizens for a sing of Mozart, Palestrina, a spiritual and, Biebl.  Ticket buyers for our concert may sign up and there was a waiting list. It's become a regular part of our Viennese life. Looking forward as always to the magnificent Musikverein.
