"I remember the night he wrote the song "Tom Joad." He said, "Pete, do you know where I can get a typewriter?" I said, "I'm staying with someone who has one." "Well, I got to write a ballad," he said. "I don't usually write ballads to order, but Victor wants me to do a whole album of Dust Bowl songs, and they say they want one about Tom Joad in The Grapes of Wrath." … Woody had a half-gallon jug of wine with him, sat down and started typing away. He would stand up every few seconds and test out a verse on his guitar and sit down and type some more. About one o'clock my friend and I got so sleepy we couldn't stay awake. In the morning we found Woody curled up on the floor under the table; the half gallon of wine was almost empty and the completed ballad was sitting near the typewriter. And it is one of his masterpieces."
