Was continuing my scanning of old Billboard magazines for Alberta radio stuff.
Along with seeing an ad from Mark Century (1968) featuring its clients business cards (including that of CKXL - wish I had a copy of the jingles) there was a story that came up from The Museum of Broadcast Communications encyclopedia of radio By Christopher H. Sterling that mentions Len Theusen being attacked and forcing CHED off the air. It notes a story in the 16 October 1972 Edmonton Journal titled "Attacker Forces CHED Off The Air." Anybody know the story? Earliest digital records for the Journal I can find only go back to the early '80s.
