Experiments are underway on the possibility of using sweet sourgum as a source for fuel ethanol, which can be grown with only about 22% of the irrigation water required for corn. This may make sourgum a viable choice for regions with water shortages.
Diamonds & Rust by Joan Baez. In this song, Joan Baez is singing to her former lover Bob Dylan, fondly reminiscing about their 1960s affair. Baez said that this gave her inspiration to write Diamonds & Rust, and that she lied to Dylan, telling him it was about David Harris, to whom she was married from 1968-1973.
And the material was fresh and unique.. Joan would later document her memories of the relationship in Diamonds and Rust, one of her best-known songs. By the time of their joint U.S. tour in early 1965, their personal relationship was coming to an end. Dylan treated Baez badly, and Joan had finally had enough.
