Found this online today while looking for sheet music on classical folk songs.
If you no habla espanol, La Curaracha means cockroach.
Lyrics vary from about a cockroach having no legs to having no reefer to smoke.
And from the sites I've read, song started during mexican revolution to the spanish american war, and even futher back, possibly to spain, during 19th century conflicts.
Anyway, that's it for now. Going to get back playing my horn.
