Garabedian embellishes the story a bit, but WMEX did very well under his reign, coming very close to and maybe even beating WRKO is some dayparts for a couple of books. Then Max Richmond died and Garabedian got fired shortly thereafter.In the early '70s WMEX made a run against WRKO with John Garabedian as PD and afternoon drive. John introduced some innovations such as a commercial free 5-6 PM hour on weekdays (introduced with a clip from "Silence is Golden" by the Tremeloes). At the time Bill Drake was consulting WRKO, and I was once told that Drake came to Boston to personally tweak WRKO to prevent erosion of listeners to WMEX.
I don't remember any commercial free hours, but it could have happened. The "Silence Is Golden" segment (actually it was the 4 Seasons' version used as a bumper) was 3 oldies back-to-back with no DJ talk.
TOH ID was pretty dramatic...crescendo from Also sprach Zarathustra followed with John G saying "changes...and you have found the new music" into a jingle ID.
Garabedian was/is an interesting fellow...his autobiography "Harmony Of Parts" is worth the read.
