Imagine Dragons' message to Canada was generic as hell. Even the way they generalized it as 'Canada'. I mean, a Canadian band playing in the US wouldn't just say 'Thank you USA!' They'd for sure specify. 'Thank you Dallas, New York, Boston, wherever'.
I thought the boy band that played at last years Grey Cup was much, much worse. But yeah, these guys were certainly nothing to write home about again. Then again, half time Grey Cup entertainment has been pretty bad for a while now.
