Google observes July 4th in its own special way

JoshuaPundit caught Google observing July 4th in its own special way.  I’m willing to attribute their decision to sheer ignorance.  Most of us learn the song they reference as a simple ode to America with a very catchy tune.  However, one would think that the Google guys could look it up.  Either they did, and liked what they saw, or they figured that, if ignorance is bliss, ’tis folly to be wise.
