@Letty,
Loved Hank as a boy and love him still. His abuse of drugs and the like likely stems from childhood illness that kept him in pain as an adult. That's more excuse than some of his descendants probably have.
Williams died at age 29; his death is widely believed to have resulted from a mixture of alcohol and drugs. His son Hank Williams, Jr., daughter Jett Williams, and grandchildren Hank Williams III, Holly Williams, and Hilary Williams are also professional singers. - Wikipedia
Hank's big hit of Lovesick Blues was not written by him.
