Gathering (dis)Organization

More esprit de corps
demand three organized
individuals. This triangle,
with its three-sided hat
and triple-color flag,
creaks songs into the
blunderbuss, all known
for their explosive,
powdery percussion.
Sing well, entente. 
Your desiderata must
join courses with the
forces of golf, Babbitt,
and Peter, your under
bear middle finicker,
managing always to 
ruin anything that 
sounded like a 
promise.
