I'm kind of curious as to what brought up the question. The reason is, CBS recently put on "Bowling For Columbine" over the air.
As far as I know, nobody ever put that movie on over-the-air TV before.
So, pardon my paranoia, but we all know the anti-gunners seem to be pulling out all the stops, and I wonder if somebody showed "God Bless America" on TV as an additional propaganda effort.
BTW, with the Fourth coming up, if you can catch the movie "1776," do so. While it is not 100% accurate, it is highly entertaining and stimulating. "Large portions of spoken and sung dialog are taken directly from the letters and memoirs of the actual participants," says IMDB.
