After seeing The Secrets of the Muppets and hearing that Henson's workshops were in New York and London, I assumed that those were the only places that Henson's productions were made (excluding obvious exceptions like The Muppet Movie being made in Hollywood). And now that I think about it, a great deal of Henson productions were made in Canada, yet I don't associate Canada with the Muppets as much. But many of the Muppet specials from the 1970s and 1980s were produced in Canada, even when the Muppets were relatively unknown. Of course in the 1980s it made a bit of sense to make more Muppet stuff in Canada. Fraggle Rock was produced there, and unlike The Muppet Show and Sesame Street when they began, Fraggle Rock employed many background performers from the start, most of whom were from canada. Making more productions in Canada provided more work for these background performers, and it especially made sense to produce the 30th anniversary special and MFC up in Canada, considering the large amount of Canadian performers and large number of Muppets used in those specials. Of course it is a wonder Henson didn't arrange for his Canadian and England-based performers to perform in the United States more often; The main Muppet performers were based in the US yet were often able to travel to England, Canada, and elsewhere, so why not non-US performers?
