Gee, Art, I havent heard that song for many a year. My older brother was in the CCC, and used to sing it. It was a true folk song in that there were hundreds of verses added by the men of the CCC. Some, like those you've given, he could sing in the house; there were many others that he sang only when we were out in the back fourty. Who says you can't have sex education through song??
BTW, his job with the CCC was planting rows of trees on farmland in North Dakota as windbreaks. Last time I was there (about 10 years ago) there were still a few around.
Also he, like a lot of others, went directly from the CCC to the Army; seemed like the thing to do for a couple years. Except that WWII came along and the two years got extended.
