Heard a rebroadcast of a 2003 interview Earl did with Terry Gross. He told some great stories and was basically just the man we know and love. At one point, he even had Louise come in and tell a story about the Beverly Hillbillies theme, because she knew the business end better. The last thing he talked about was his banjo.
