How Montreal, with Hypermarche, brought the megastore to North America

Hypermarche, complete with 70s hippie truckin' down the aisle

   Hypermarche advertised itself as the first supersized supermarket in North America when it opened October 31, 1973 at the cost of $11 million, bankrolled by Oshawa Group of Toronto and Mondev of Montreal.
   It sat at the Centre 2000 Laval (now part of Centropolis) and was managed by someone named Glyn Hacking.
   He said the only drawback was that customers sometimes get tired from all the walking.
   The concept originated in France but apparently this was the first in North America. They planned to open another one in Montreal sometime in 1975 but somewhere along the line they obviously went broke.
   The concept, as we know, took hold in megastores like CostCo and others.
   I appear to have burdened, cursed, afflicted by a nauseating impulse to play the song from the Hypermarche TV ad in my head all the time but I can't find a recorded version anywhere. It seems to only exist in my brain matter.
  Me and Chimples, the brain-implanted simian seem to be the only ones alive to know how it goes: "I'm going to build the largest store i
n North America.. a food and discount store in one great area.... something something something, .. a thousand different items piled up to the sky ... and (chorus - tempo change, sorta can-can style) and.. the higher we pile them, the lower we price them, the lower we price them, the more you buy them... "
   I was really hoping that one of those YT nerds who puts old Kweebeck schlock on the internet would eventually find and post this but to no avail.
