In the 11th International Festival of the Lute, Kassel - Germany2007, 18th to 20th of May, there seems to have been a lecture of this matter: Dr. Frank Legl (Weilheim/Germany): "Johann Caspar Goethe und die Laute".
Perhaps someone in the List was there or even knows Dr. Legl? All the best, Arto To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
