Bob Cole went from AM to FM, and played freeform at night for a couple years before the FM went 24-hours. Even then, late night may have been freeform.
The first WKDA-FM survey i have is dated 4/6/70.
Singles: 1. Let it Be-Beatles, 2. Spirit in the Sky-Norman Greenbaum, 3. Instant Karma-John Lennon, 4. Bridge Over Troubled Water-Simon & Garfunkle, 5. House of the Rising Sun-Frijid Pink, 6. Come & Get It-Badfinger, 7. American Woman-Guess Who 8. Something's Burning-First Edition, 9. Woodstock-CSNY, 10. Love Minus Zero-No Limit-Turley Richards. Nothing you wouldn't hear on AM pop radio.

Nothing bold or unusual or obscure, certainly nothing "underground"
11/9/70 includes songs by Bread, the Carpenters, Christie, the New Seekers, Diana Ross, Neil Diamond & the [new] Supremes. By the time i started college fall of '72, they were playing, as i mentioned, " 'outlaw country', select album cuts, and IIRC, comedy & oldies."
AM went country March or April '70. 5/19/75 listed songs from Charlie Daniels, Marshall Tucker, Paul Davis, Amazing Rhythm Aces,
Dave Mason, J.J. Cale, Jerry Jeff Walker,
Bob Dylan Was their music country? Yes, to varying degrees. Did most country stations play it? No.
... I don't remember ever hearing Helen Reddy or the Bee Gees, though...
9/9/72 #12 I am Woman-Helen R, #19 Run to Me-Bee Gees
