@Q: Since you gave the address of the site you copied it from, it was clear that the errors and the weird lining weren't yours.
The lyrics with the question marks can be found there.
I'm more familiar with the original version. There's also some spoof lines that go "Si a tu ventana llega un perro chato, trátalo con cariño que es tu retrato." (If a pug-nosed dog comes to your window, treat him with affection/love for it's your portrait) and "Si a tu ventana llega una sombra oscura, pégale un garrotazo porque es un cura" (If a dark shadow comes to your window, hit it with a stick for it's a priest). I don't know if the last version is related to the Spanish Civil War atmosphere.
