Yes, briefly.
"Radio 11" WKYC's long-time morning show (back to the KYW days) was (Harry) Martin and (Specs) Howard. They left sometime in 1967, and C&H came in, staying for a good year and 1/2.
Big Jack Armstrong came over from WIXY just about January of '67 and stayed through almost that full year. Which was fortituous, because shortly--like weeks--after Jack left, WKYC blew out the staff and bowed "Power Radio" which was a pseudo-Drake format helmed by Hal Moore.
The 1967 WKYC Radio 11 staff would have included Martin & Howard/Charlie & Harrigan, Bob Cole, Chuck Dann, Jay Lawrence, Jim LaBarbara, and Big Jack. (LaBarbara moved to WIXY when Jack Armstrong left for WKYC.)
The 1968 Power Radio staff included C&H, Chuck Dunaway, Fred Winston, Buddy Henderson (later Ed Mitchell at CKLW and Mark Elliott at KHJ--now the voice of the Disney movie trailers), Bill Winters (later at CKLW), Bobby Shannon, Lee Baby Simms, and Bob Cole stayed for a few months after the transition.
