Here are a few from in and out of the Portland area:
Alan Mason became Mike Rivers on KGW….he did not work at KVAN.
Joe Gianunnzio became Joe Cooper on KGW….mostly because no one could spell his last name…it may be wrong here. This was accomplished in a high level meeting in my office using a phone book and a pencil.
Fred Wasnuski (phonetic but not correct spelling) became Fred Winston on KOIL, WING, WKYC, WLS and others…..mainly because he wanted it that way.
Lyle Lebsack beame Lyle Dean on KOIL, WLS, WGN…..”Dean” is Lyle’s middle name.
KISN’s “Jim Hunter” became Roger W. Morgan on KOIL and later KISN because I was at KOIL before he got there and I was using Jim Hunter. Also because Burden wanted a “Roger W. Morgan” in the morning and Burden usually got what he wanted.
Bob Bengsten became Bob Benson on KOIL, WLS where he was News Director and later as head of Radio network News at ABC.
Don Rossi became Uncle Don Wright on KGW.
Dan Foley, Phil Harper and Gordy Miller’s names were not changed at KGW. Gordy called the KGW Production facility “Buck Central.” He was right.
Al Vanik became Gary Mitchell on KING-AM.
Bill Neeck became Todd Chase on KOIL, and later KQV, WQAM and others.
Mike Hankins became Mike McCormick on KAAY, KOIL as PD, KQV as PD, WLS as PD.
Bruce Vial became Johnny Mitchell on KOIL, and then legally changed his name to Kris Eric Stevens at WLS. As he grew as a person, his personna changed and he once told me that “Bruce wasn’t who he was anymore.”
Many of the early “house names” were originated in an attempt to tie into various things, like time periods. At KAAY the afternoon drive guy was “Buddy Carr,” and there are many others I’m sure you can remember.
Sometimes the change was made to make singing a jock name jingle easier. It was really hard to get the PAMS singers to get names like Larry Lujack, Dan Ingram, Pat O’Day, etc. sung right so they fit with the call letter musical logos. That’s one reason why there were “jock shouts.” The singers would enthusiastically shout the name in unison. It solved a lot of matching problems.
