There was a Sun-Times' feature story years ago about Allan Stagg and his old "Sanctuary" overnight show that used to air 6 nights a week on the long defunct CD 94.7 FM during its Classic Rock identity.

There was a photo of Stagg, who looked like a cross between Howard Hesseman, the actor who played Dr. Johnny Fever on "WKRP in Cincinnati" & Charlie Moore on "Head of the Class", and The Who's Pete Townshend outside the radio station's studio at 190 N. State, which is ABC 7's famous address. Back then, it was also the home of WLS-AM 890, 94.7 FM and most recently, ESPN Radio 1000 AM before all 3 stations relocated. Stagg looked like he was posing for an album cover and had a thing for smoking cigarettes when he wasn't in the studio when the Sun-Times took a photo coinciding with the feature story I read about.

There are still a few clips of Stagg's old "Sanctuary", complete with movie & TV soundbites & various sound effects to make the show sound like what FM radio sounded like decades ago available on YouTube if you're interested.
