Sad news, indeed. I saw Sonya on a number of occasions when she was living in London with her parents, John & Penny. She was a lively child with a great enthusiasm for so many things and I am glad to see that she later spent her life doing so much. I often play a track of her singing "Who'll Water My Flowers?" (on Smithsonian Folkways SFW CD 40091)when I need to hear something beautiful. My thoughts are with John and the rest of her family.
