I believe I am using the right word here - are the rhytmic chants of sergeants giving rhythm to marchin soldiers not called "cadences"? Plese correct me if I am wrong. In any case, assuming this is the right word...

...it strikes me that cadences are kind of working songs too, like the shanties (chanteys) of old. Sort of latter-day shanties.

Why not collect some of them (and I bet there are some real gems out there!) and even try them out in clubs?

Looking towards our American brethren mostly for inspiration, though I believe the UK armed forces use them too.
