The Orange Crush has gotten so good at national-anthem singing, it can even do "The Star-Spangled Banner" without a lead singer.

After Brett Kissel's microphone was not being picked up inside Rogers Place (it could, however, be heard on the TV broadcast) before Game 3 of the Western Conference Second Round between the Anaheim Ducks and Edmonton Oilers, the country-music star solicited help from the crowd.
Not only did the Oilers faithful know all the words, they delivered a chill-inducing rendition of the American anthem.

After warming up with the U.S. anthem, the fans sang "O Canada" along with Robert Clark, continuing their Stanley Cup Playoff tradition of belting out the Canadian anthem as one unit.
