I have a book, which I can't find now, of course, called Charmed Circle, a very good modern biography of Gertrude Stein and Alice B. Toklas and their circle of friends. There is a photo of Gertrude at about sixty, outdoors at their home in rural France, leaning back and singing 'her favourite song', On the Trail of the Lonesome Pine. She is holding a copy of the sheet music. If I find the book, I'll add the date.
