Taylor Swift and Kellie Pickler Tackle Toby Keith

Taylor Swift and Kellie Pickler flexed some patriotic muscle at their recent Army Concert Tour stop in Huntsville, Alabama. The BFFs performed a duet of Toby Keith's 'Courtesy of the Red White and Blue (The Angry American).' This video, originally posted on a fan's MySpace page, starts off with the ladies singing a Corinne Bailey Rae song before breaking into their Keith cover.
