In the late thirties and early forties, my Dad was on staff at a military school. He would sing the first line, start laughing, and refuse to sing the rest. Many of the students would do the same, at Parade and Pass in Review.
Then after WWII, after my uncles came home from overseas, the singing would start up again...always only the first line, accompanied by much laughter.
I have spent my entire life (from time to time) wondering how the song continued.
Thanks, everybody
