I took video footage, but can't seem to upload it. For now, just imagine a bus full of kids singing "Yankee Doodle," "50 Nifty United States," "1814," and much, much more... all at the top of their lungs.
It feels good to know that they love what they've learned! Neither they nor we will ever forget this impromptu patriotic bus sing-along.
You can watch the video on YouTube (although the video is unlisted so only those given a direct link like this one can watch it):
