I'm not sure (although I think it was) if it was produced
in Canada, but "The Ian Tyson Show" was hosted by a
Canadian folk singer who, with his wife Sylvia, were part
of the folk boom of the early '60s and made frequent appearances
on ABC's "Hootenanny." Ian's show was syndicated in the U.S.;
I recall seeing it a time or two on WLOS around 1970.
The PBS station in Athens, GA, WGTV, used to carry a show which
was produced in Canada, "The Irish Rovers." Remember them and
their big hit "The Unicorn"?
