WCMF was a wonderful station. They had begun as part-time free form but were full time by the time of this air check from Aug 1972. I believe they also had a power increase around this time and that is when I began to listen in Toronto when the atmospherics allowed.
The DJ is Tom Teuber who also worked in Buffalo among other places. You will also hear “Unkle” Roger McCall on a few ads. He was newly arrived at the station from WPHD FM in Buffalo. The track selection is diverse and includes Pentangle, Lindisfarne, Brewer and Shipley, the comedy of the Firesign Theatre and more in this excellent example of progressive radio.
