The aircheck you might be referring to is rare. I have the only copy. It's Terry Steele from CHUM who was a very dear friend and along with Tom Rivers and Mike Cooper my mentors.
Terry and I drove to CHIC in Brampton one night (where I started) and Terry did an hour on the air as Farley Schwogmore. It was hilarious. I operated and the kid doing all-nights stood back with his mouth open in disbelief.
Maybe I'll have it digitalized too. The funniest part of it is that CHIC had lousy equipment and no compression. Terry's voice boomed over the entire mix. Ah, the crazy days of summer!!
