New Hampshire Wants To Become Part Of Canada?

Today, while watching the pre-race festivities of the NASCAR Camping World Truck Series race, in Louden, New Hampshire, at the New Hampshire Motor Speedway, I was kind of shocked they sang the Canadian National Anthem.
Loudon is located in the east/central area of the State of New Hampshire, no where close to Canada. New Hampshire shares it's northern border with Canada and it's only for a few miles.
The sponsor of the race is from Massachusetts, not Canada and the owner of the track is not Canadian.
So, why the Canadian national anthem? Perhaps they should also play the Japanese national anthem because they have Toyota trucks in the race.
I can understand if the race track or Loudon bordered Canada or if the race was in Vermont, then they would do something for Canada, but that's not the case. So, why is the Canadian national anthem being sung here?
Pretty soon, in Las Vegas, we may sing the Mexican national anthem at the 51's minor league baseball games.
Just curious.
