I recall it quite well. During U.S. Army basic training at Ft. Leonard Wood MO, in Jan. of 1964 a bunch of us recruits were sitting around after some exercise or other and the subject of relatives in the military came up. My grandfather had been in the 69th New York (an Irish outfit) during WWI, and he had told a story about a famous newspaper photo showing the 69th marching to France, caption said they were watched over by a priest and were singing onward christian soldiers. He said no way, if they sang that protestant song the priest would have cursed them. They were actually singing a very bawdy tune called "Bangin' Away on Lulu!" I had overheard my father singing a couple verses of that tune, and I sang them. Several of the other guys knew the tune and had their own verses, and then the subject changed to bawdy old songs and the Madamoiselle and same thing - verses contributed by various guys - pretty rank stuff, although funny. I had no idea how bawdy it was a until then.
