(Dan Fog : Kompositionen von F. Kuhlau Thematisch-bibliographischer Katalog）1977

This score was considered as lost until now. This discovery is a credit to Dr. Busk. He had inquired to various libraries about the "Variations" of Kuhlau. Mr. François-Pierre Goy in the National Library of France has helped Dr. Busk.
Variations on this theme: Romance "Lorsque dans une Tour obscure" in the opera "Prisonnier" of Della Maria.
This opera had been staged in Hamburg that time.
Pierre-Antoine-Dominique Della-Maria (1769-1800)
It will become apparent Kulau's activity of his Humburger-time, and also relationship with Schwenke.
