Daytime was WKLO or WAKY with the Duke of Louisville, Bill Bailey, holding down the morning shift.  In the late, late evening it was WLS.  

Most vivid memory of WLS was the Mr. Norms Grand-Spaulding Dodge commercials along with the ????? (memory is not so good after all) dragway commercials.  What was the name of the dragstrip where they had all the big name racers back in the 60's and 70's running funny car match races, etc??
