Which FM station were you listening to in the 70's?
In Boston the coolest FM station was WBCN.
The late 70's was it's golden era. Billy West (The voice for Ren & Stimpy, etc) did voices and promos. Areosmith, shared airtime with Gil Scott-Heron, Jonathan Richman and the Modern Lovers and the Beatles
There was the morning game show-Mishegas, The lunch-time song where popular songs of the time had their lyrics replaced with lunch-time themes. "Here comes the Chung-King" "Slattered" Electric Barbecue" etc. And the 5:00 Comedy.
The DJs were entertaining without dumbing down the content and great bands were coming out of Boston at the time.
WBCN wasn't the only station, in the early-mid 70's there was also WBZ-FM with Captain Ken Shelton who would scratch a newly released commercial song on the air and name it the WBZ-FM Bummer Record of the week!
