In defense of Rufus Wainwright, a Canadian-American who sang the National Anthem at Dodger Stadium prior to Game 5 of the World Series, mistakes happen.
It's understandable that singing in front of 40,000+ fans can be daunting. Additionally, it seems many American fans didn't notice Wainwright's clerical error.

It's been a tough year for Canada-United States relations.
