No, this is not a 9/11 tribute, technically. This is an earlier performance from a sporting event. Still, on this sixth anniversary of the terrible tragedy that occurred on American soil, I can think of no better tribute to the fallen and to the heroes than our own national anthem, and I can think of no one better to sing it than Kristin Chenoweth. Set your work aside for a moment, turn up your speakers, and just . . . listen.
