Edmonton's fans sing US National Anthem in amazing moment!

The Oilers fans are known to be very patriotic and highly enthusiastic about their own team. However, in a classy turn of event today, Brett Kissel got the Edmonton's crowd into signing the Stars Spangled-Banner!

How awesome is that? Signing the national anthem a Capella has become a common occurrence in the NHL, but singing the other country's is just pure class. 

Well done Oilers fans, well done.
