Here's a short story:

Woody Guthrie left California for New York in 1940. There he met Alan Lomax, an expert on America's traditional music. He collected and recorded traditional American folk music, which had few fans at that time. When he heard Woody sing, Lomax knew he had found a true singer of American folk music. Lomax recorded many of Woody's songs for the Library of Congress. 

Three years later, Woody published a book called Bound for Glory. It was about his early life and travels. From this book people came to learn how Woody had spent his unhappy youth. His mother, Nora Guthrie, died of Huntington's Disease in 1929 when he was only seventeen years old. There was no treatment for the disease. About twenty years later, the disease also began to attack the son. Woody's health got worse and worse, and finally he entered a hospital. 

While Woody seemed to be forgotten, his music was not. By the late 1950s, folk music became popular in America. More Americans began listening and playing the songs of Woody Guthrie. Young folk singers came to New York to visit Woody in the hospital. Among them was Bob Dylan, one of America's greatest popular songwriters. He called Woody his hero. Dylan and others copied the way Woody sang and played the guitar. And like Woody, they wrote songs that called for social and political justice . 

Woody Guthrie stayed in the hospital until he died in 1967. In the last years of his life, Woody could hardly speak. But his family and friends knew he still believed in the causes he had sung and written about all his life. They knew this because when they sang his songs, Woody's eyes would become brighter and his defiant spirit would shine through. (End of story)
