Programme notes off the web; I haven't seen the score. In many of RVW's pieces only the first tune of a group is actually named. First time I ever heard his "Greensleeves", I noticed that it included Lovely Joan. Mentioned that to the bloke who had played it; he had had no idea, and had assumed that it was a variation on the Greensleeves tune. Percy Grainger was more forthcoming about his sources.
