Easy to guess because of the famous rider.

English-German-French-English:

Yankee Doodle Ritt zur at the city
after small Pony;
it adhered a feather on its hat
and city the maccaroni.

But I think is even better: English-Portuguese-English:

Yankee Doodle mounted to the city
in top of a small pony;
he pierced a penalty in its hat
and called it maccaroni.
