Derwood Flange

 Derwood Flange, if memory serves was a character used in 7-11 Canada radio ads in the early to mid 80s./  I Google  / YouTube searched  any kind of reinforcement of this and I don't seem to find anything . 7-11 back then was Slurpees , wheelies and burritos . Now that I am in the Philippines , 7-11 has decent coffee plus the chocolate section and Heineken . No sign of Derwood Flange.
