Willie Dawahare was Mayor of Hazard from 1962-69. Then Bill Morton was from 1970-77. From WSGS.com you can click on history and look at pictures and information there. You might want to write email@example.com. I think they had a lot of old history items. He might be able to give you some good ideas and direct you to information from the time period you want. The suggestion to go to library if you are in the area is an excellent place to look. Good Luck.
Martha Quigley at Bobby Davis Park Museum on Walnut St. might be a good person to talk to as well. 439-4325. I found this on WSGS history: WSGS (101.1 FM) is a radio station based in Hazard, Kentucky. The station first began broadcasting in the 1950s as the first FM station in the East Kentucky Coal Fields During the 1960s WSGS held the distinction of being the most powerful FM in the state. Today - WSGS broadcasts a 100,000 watt signal and has a greater coverage area than any FM station in Kentucky based on FM Atlas, a national publication. The station was the first in Kentucky to broadcast a Country music format on the FM dial. In the 1960s the "easy listening" format dominated most FM stations in the United States. The station began playing Country Music on a full-time basis in 1968
