An absolute giant of Canadian music, one of our all-time greatest exports to the entertainment world.
I worked in the photo/video department of Canon Canada for three years in the mid-to-late 90s. Canon's office was in Mississauga and Peterson was a neighbour of the president of the company. Peterson was a photography nut and only used Canon stuff. He periodically sent stuff in for servicing and one of our camera repair guys would fix it and drive it back to his place. I was asked to tag along on occasion but could never fit it into my schedule.
If I'd gone I probably would have just ended up sitting there like an idiot until I could get thge balls to ask him about that famous recording he played on of Ella Fitzgerald screwing up the words to "Mack the Knife".
