Reaction on social media to singer Nelly Furtado's unconventional rendition of O Canada at the NBA All-Star Game on Sunday night was swift and harsh.

The B.C. songstress sang a slow, melodious version of the national anthem, accompanied by Native American flutist Tony Duncan on an instrument made by Saskatoon's Richard Dubé.

The performance drew big cheers and applause from the crowd at the Air Canada Centre. 

But those watching at home and tweeting were less than impressed. CBC Toronto asked its Twitter followers what they thought, and the reactions were not kind.

It didn't take long before the singer was trending on Twitter for all the wrong reasons. 

Though some folks still had some love for the I'm Like A Bird singer.

Before Furtado took the stage, Ne-Yo performed a low-key version of the U.S. national anthem. Later, Sting ran through a collection of his hit songs during the half-time show.
