Anyone who says Canadians are polite hasn't gone on Twitter while the national anthem is sung on TV.
Before kickoff at Sunday's Grey Cup, fans were treated to a singalong version of the national anthem led by Choir Choir Choir. But many fans didn't think it was a treat at all.
Some didn't like the pop tone.
I'm actually mad about that version of O Canada. It's our national anthem, not a pop sing-along for your next single. #GreyCup— Kate Goodhelpsen (@kgoodhelp) November 26, 2017
Some thought it was too rushed.
What are they doing to the Canadian anthem? It isn't a race to the end of the song! #GreyCup— Sharon (@saskie35) November 26, 2017
Some were angry.
Imma just pretend this anthem never happened. Let's never speak of it again. #GreyCup— Tony Allen (@TonyRougeRadio) November 26, 2017
Anybody watching whatever this anthem performance is? Is this the Grey Cup or a middle school assembly? #GREYCUP— Jeff McEnery (@JeffMcEnery) November 26, 2017
@CFL what the fuck was that version of the anthem?!?! Nobody asked for a God damn campfire sing-along. That was a fucking disgrace to Canada. How the hell did you guys decided and then approve that?!?! You guys really fucked up this one!! #GreyCup#GreyCup2017— Calvin Lee 🇨🇦 (@calvinstampsfan) November 26, 2017
Respect your national anthem, get off the field #GreyCup— HabsFanInTO (@HabsFanInTO) November 26, 2017
One guy likened it to, um, terrorism.
The dudes that sang the national anthem at the #GreyCup should be tried for domestic terrorism.— Ryan is a cool Dude (@RyanisaCoolDude) November 26, 2017
Others chimed in to say it was just fine — or, the greatest rendition of O Canada ever.
That national anthem was fine and everyone should stop being so grumpy about it #greycup— Festive Eric Bell 🔔❄️🎄 (@eric_bellMB) November 26, 2017
Just starting the #GreyCup on PVR, and without knowing what the Twitterverse thought, I loved that snowy introduction and anthem!— Jeremy (@Johnny_Canuck_) November 26, 2017
We don't all have to be crusty ol' grumps all the time. It's okay to think that was a cool way to do the national anthem. #greycup— Mike McKinnon (@mikemckinnon) November 26, 2017
Canadians are known to be merciless when it comes to creative renditions of the song. Nelly Furtado learned that the hard way when she sang O Canada at the NBA All-Star game in 2016. And one MP's successful bid to officially change the wording of the song sparked a very emotional debate.
