Delta, Correction for you.
Chickenman was produced/recorded (NEVER live) by Dick Orkin in the production studio (located in the room adjacent to the broadcast studio) at WCFL, at Marina City, Chicago.It's been syndicated for over 40 years.
It is the same room that produced "the Tooth Fairy," "the capsule countdown" "Preview!" with a 10 second cut of the song that would follow the news, and many other wonderful CFL production pieces.
Orkin is stilll doing commercials. I hear, "The Chicagoland New Car Dealers Asoc" ad on wgn, sometimes using his voice in a clever piece,
and there is also a bank with a very clever ad, about car poolng with a guy (Voiced by Orkin), who has no car. It's great.
Peter Fugitive is the late Art Roberts creation, at WLS.
You're Welcome!
