Do you just want him to perform or to be interviewed? "The Tommy Hunter Show" is about the right period, there were guest performers, but I don't recall much talking. Maybe rather than a music show, you should have him on a talk show. Or, does the audience have to see him? I'll bet the CBC, then as now, interviewed a lot of local talent and played a couple of their songs on the radio. Or, if he did anything newsworthy, or had a hit, how about "Front Page Challenge"? I don't recall that they were all 'big names' - quirky and newsworthy would do it. And you don't get more Canadian than "Front Page Challenge".
