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.
Diamonds and Pearls features a hybrid of music styles, from the funk of Daddy Pop, Jughead, and first single Gett Off, to some of the more mainstream pop/rock songs Prince had recorded in some time, such as Cream, Money Don't Matter 2 Night and the title song.
