Other than Willie Nelson, what artists inspired the title cut for the album "Waves of Grain"? 
Amber Waves of Grain:  The title cut, written by Freddy Powers, is a paean to the American farmer, in keeping with the spirit of the Willie Nelson-spearheaded Farm Aid benefit, as does "Tulare Dust" and "The Farmer's Daughter." Farm Aid:  The concert was organized by Willie Nelson, John Mellencamp and Neil Young, spurred on by Bob Dylan's comments at Live Aid earlier in that year that he hoped some of the money would help American farmers in danger of losing their farms through mortgage debt.
