Kansas' Constiuents singing "This Land is Your Land"

So I went to How it Ends. A lobbying event with Invisible Children, trying to get congress to cosponsor a bill that would stop the longest running war in Africa. While we were talking to Congressmen Dennis Moore's Secratary, we told her why we wanted this passed, we went into Dennis Moore's office at least 3 different times and he always called us back in, but at one point he pulled out his guitar and we sang this land is your land with him. We all thought he was a mean serious man, so it was just so suprising that he would sing with us. Ever since then I have really changed my perspective on this man. And he is really a cool guy.
