Thanks to all for your examples, comments, and links.

I've been interested in the origins of children's rhymes for some time and never thought that military cadences could be a source for these rhymes. Neither did I think that spirituals such as "Aint Gonna Grieve, My Lord, No More" could be a source for these rhymes.

I had found that contemporary children's rhymes use lines from Mother Goose rhymes, other children's rhymes, cheerleader cheers,
TV/radio commercial jingles and script lines, commercial product jingles {like McDonald's "You deserve a break today..", signature phrases from TV characters; Mardi Gras Wild Indian chants, and titles and lines from recorded dance music, particularly R&B and hip hop.

Thanks to Mudcat posts, I now include military cadences and spirituals to that list of sources for children's rhymes. Since I hadn't previously studied military cadences, I also wasn't aware of how many of the lines from those chants were "inspired" by spirituals and children's rhymes.

As a result of reading the Mudcat threads on "Jodies" and reading additional examples of these chants on other websites, it seems to me that similar to children's rhymes, the anonymous composers of military cadences appear to be be alert to any source that can be used to make up their chants.

My thanks to you all for helping me to broaden my horizons, in more way than one!

Happy New Year!
