This historic trove of lost Williams recordings was originally broadcast on Tennessee radio in the early 1950s. In addition to rare versions of Williams standards like "Hey, Good Lookin' " and "I'm So Lonesome I Could Cry," the set also includes dozens of previously unknown covers, from "On Top of Old Smoky" to "When the Saints Go Marchin' In." "This is like taking the Beatles or Elvis Presley, and 50 years after their deaths, finding 50 percent more music," says Hank's daughter Jett. "I'll bet the farm it never happens again."
