To the tune of Battle Hymn of the Republic.
From memory, sorry if I screw it up.
Mine eyes have seen the horror of the coming of the Reds,
They are hiding in the treetops, they are hiding beneath our beds,
Mad Magazine, had to be late 50's or early 60's.
Probably had more to worry about then than now, from the 'commies' is my guess.
