Video of kids singing

I could not get it figured out how to put this on from youtube but my father in law recorded a video chat we had with them the other day and then posted it on youtube so we could watch it again. Anyways it is Porter and Nickelle performing some songs. They may not know the words to well but the tunes they have done. If you get a chance check this out.
