Ahhh… Glad you mentioned the “True Oldies Channel” moniker which began use while the call was still WZZN, and I believe continued to be used for a short time after 94.7 switched callsign to WLS-FM.

What years did WRLL play oldies under the name “Real Oldies 1690”? I know that station first signed on with that callsign, and brought back Larry Lujack and Tommy Edwards as an encore to their years on Musicradio 89 WLS. I was wondering if Real Oldies overlapped any of the years for True Oldies Channel.
