A couple of days ago, I wrote on Judge Roy Moore's comments about Keith Ellison, the first Muslim to be elected to Congress. I pointed out that there is no contemporary evidence to support Moore's assertion that George Washington added "So help me God" to his oath of office, and in fact there's no evidence that any president did so until 1881 (Chester A. Arthur).
Little did I know that Michael Newdow, America's most famous atheist, had already written and performed a song about exactly that fact. Ray Soller sent me a link to Newdow's website, which has a short and wonderful video of Newdow singing "So Help Me God (He Didn't Say It)."
Thanks, Ray!
