A difficult question. I am not sure where to post this thread, so I hope you don't mind if I may enquire here? I have read somewhere - I think it was by John Eliot Gardner who said this - that Beethoven used a theme by Rouget de I'Isle, from his work 'Hymne dithyrambique' sur la conjuration de Robesierre, for his Fifth Symphony. I have never heard anything about this work and I am interested to find out. Does anyone know more about this?. Regards Pearly
