ACC was on just about everyone of The Hip tours for the last 10-15 years.
They sold out all the smaller venues they played in Canada.
I was at there show when they played the Centre-n-the-Square theater here in Kitchener a few years ago, not one empty seat. In the last year I've seen ZZ Top and David Crosby in the same theater and neither sold out.
No one said they were the "greatest band ever". What they were was the greatest "Canadian" band ever, at least in my book and for many others. Sure, there are bands like Rush, Neil Young and Crazy Horse and the Guess Who but those bands had much of their success outside of Canada as well as at home. The Tragically Hip were super stars at home while the rest of the world essentially ignored them. They were just too Canadian.
