Dear Marquis,
Thank you for your letter
The brilliant research of Luca Bianchini deserves credit for bringing together all of the documentary evidence in this PDF - the most detailed article on the hoax of 1770 which has so far been published.

I hope you find it interesting and informative. It is a small but basic part of the ongoing criticism of the cultural and musical myth that is Mozart. There are more than a dozen similar articles that will shortly become available.
Yanni will no doubt join in congratulating Mr Bianchini for this outstanding work.
Regards
Robert Newman
