So, this probably started in the 70's, but it continued into the 80's. Bands used to records station-specific versions of songs (Reunion's "Life is a Rock (But the Radio Rolled Me)" is one such tune, as is the tune "Fire" by The Pointer Sisters).
I'm trying to re-create the WLS/WABC New Year's Time Sweep, and I'm looking for a few regionalized recordings. I don't even know if they ever pressed them into records.
Anyone have any of these, keyed to a specific radio station?
