In the late 70's Bobby Denton gave up afternoon drive at WIVK but stayed on the air. Bobby moved to the 10a-noon slot and was followed by Ed Brantley at noon and Your Dave Young at 3p. At that time the AM and FM had been split daily between 10a-3p.
It's always fun when you hear Bobby saying your name, on this 101 Audio Vault he mentions that I am on the air that day subbing for Ed.
