Wonderful to read all the memories about Jonathan tonight. Many of my own to add......maybe later. Jonathan's essence is in his songs. His warmth, humor, intelligence, eclecticism and, even, his eccentricities are all in his wonderful music. Jonathan had an impact on everyone he ever met, whether a one-time dinner companion at his favorite restaurant or a longtime music or science/space friend. The memories and messages are pouring in from around the country from his friends in the Folk Music community and the Science News community. Jonathan stories are being told and his music is being played and sung . Sounds like he is still with us all. Mia Gardiner
