This was the Toronto stadium concert of the summer - Genesis with Brand X opening, and Max Webster second on the bill. The attendance was about 31,000.
A fan recalls: "During Max's set, someone on field level grabbed a cop's hat and began tossing it around. It caused enough of a commotion during the song that even Kim was making comments about it afterwards."
See Aardvark's Attic for an amusing story from this date.
