Dear George, Thank you for your encouraging comment and for pointing out the later Scherchen performance. I don't know how this escaped me before but I have now managed to locate it. However, rather than create infinite confusion by posting revised versions of these articles every time a new performance turns up, or a source is found for a recording I noted as unavailable (a couple of other things have been found or are promised), I will let this material accumulate for a while. Meanwhile, the series is continuing.
