Top-40 on 106.9 goes back to 1970 or 1971 when it was still Taft-owned WBRC-FM. But by 1972-73, under Mooney, what was then called "Stereo Rock ERC-FM" was a laid back top-40/AOR hybrid .... at least going by what is on the several airchecks I have. One late-night run of tape, with a jock by the name of "Captain Jack", was most decidedly progressive -- right down to the wind chimes in the background and tip-off about a pending pot-party bust.
Part of the time, 106.9 was simulcast with the AM; as a kid I recall the "WERC-AM and FM" legal IDs.
Which brings me to one huge mystery: along about August 1973, with a jock named Dan Enright, the call letters were WERQ. What was up with that, and how long did it last?? It couldn't have been too long, because it was back to WERC-FM by '74 or so.
In any event, what I think Charles meant about his "brought top-40" comment was that Kicks 106 by most all accounts was the first FM hit music station in the market to be on the map; other past attempts (didn't WAPI-FM 94.5 dabble in a full top-40 automated format for a brief while in the early-mid '70s?) were hampered by other factors -- automation, low power (I don't think 106.9 went to a full 100 kW until just prior to the launch of Kicks) and simply being ahead of their time. A station in Montgomery comes to mind: for about 20 minutes or so, 103.3 was doing top-40 as "Z-103" (WMGZ), basically a carbon copy of Atlanta's "Z-93." Despite a good presentation, it didn't last but a couple of years; the problems were they barely made it 25 miles out, plus at the time a lack of FM penetration among its target.
