Help with some (semi?) Spanish song lyrics

"Dos Tacos De Chorizo Por Favor" - a terrific song, and one that uses only two chords, so that even I can sort of play it.

Here are the lyrics I have so far, with the bits I'm most sure I have wrong noted in red. Help from anyone who knows Spanish better than I do (i.e., most) is requested.

Dos tacos de chorizo por favor

I've been drinking all night and my head is so sore

Maybe some menudo, I've got to have some food

Oh, dos tacos de chorizo por favor



I went to the cantina, with my bonita Gina

The prettiest girl in San Antone

But I got muy ogracho, and she ran off with Nacho [ed - ha!]

And now I'm drunk and hungry and alone



So, dos tacos.....



(instrumental)



I went back to the cantina

'Cause drinking helps a broken corazon

And when I left the bar, la policia towed my car

And I couldn't find my way back home



So, dos tacos.....



(key change)



Dos tacos de chorizo por favor

I've been drinking all night and my head is so sore

Or maybe some menudo, porque ando muy crudo

Oh, dos tacos de chorizo por favor



Dos tacos de chorizo por favor!

Thanks!
