Who would have guessed that Canadian hockey fans would sing the most beautiful rendition of The Star-Spangled Banner?

Brett Kissel on Oilers fans saving anthem: 'It was a magical moment' 4:35

That's what happened in Edmonton on Sunday night at Rogers Place, before the Oilers' Western Conference semifinal game against the Anaheim Ducks. The fans stepped in to help out country star Brett Kissel after it appeared his microphone failed during the U.S. national anthem.

Kissel, who was born in Flat Lake, was grateful as the sellout crowd of 18,347 showed him some Alberta love.

Even right-wing U.S. media organization Breitbart News took notice.
