I read with interest that La Cucaracha was the marching song of General Pancho Villa's troops, and have found this translation:

La cucaracha, that little cockroach,
O his home he'll never leave,
because to travel without a real roach to smoke,
he just can't conceive.

Heard the cockroach kicked the bucket,
and the funeral packed the house.
He was buried with four buzzards,
right next to the sexton's mouse.

With the chin hairs of Carranza,
I will weave a lovely band,
for the hat of Pancho Villa,
yes, our leader oh so grand.

When this baker went to mass,
he didn't have a single prayer,
so he prayed the blessed Virgin,
fill his pot pipe up to there.

Biggest laugh that I've had ever,
Pancho Villa without shirt on.
Carrancistas run for cover,
that's why Pancho Villa's men won.

There are various CDs listed as "music of the Mexican revolution" - but which are good, and which are authentic?
