I played the tune in a bar in Rochester and a young man came up and asked what the name of it was. He said he was a music scholar and had just read the tune in a 13th century manuscript.
Near Portland Oregon I watched some excellent Estonian folk dancers with a wide traditional repertoire. When they did a dance using Soldiers Joy on fiddle I ran around back and asked them about the tune. They said, "oh, we call that one 'der Engelsk ton' - the English tune."
