'Mornin', Guest--

The song you mention was an extremely popular participatory folk song when I was in Infantry School at Fort Benning. As the troop trucks were hauling all us green second lieutenants out to Liberty Pond or some such place, we would sing the chorus, and when someone had a filty limerick in mind, he would raise his hand and sing it; then we'd sing the chorus again, and another feller would raise his hand, do his solo, and we'd hit the chorus again. Sometimes we would go for half an hour or more without ever repeating a limerick (as you might expect from a truckful of ROTC cadets just out of four years of college fraternity life). As Midchuck says, there are no fixed verses, as far as I know, but the Legman book is available, I think.
