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.
General CommentI don't think Diamonds and Rust reveals 'tears and then dried.' What I think it means is, as in all wonderful, set apart relationships, there is 'diamonds'..the closeness..the good times. And 'rust'..the end. Joan sings 'I've already paid'..her heart has already broken once and one more telephone call will not change that. There is another song that Joan sings for Bob.. What really is the core issue is: Did Bob really love Joan or was she just a 'deviation' for him when he broke up with Suze.
