It is a lively and fun song. It would also never, ever, be allowed by today's "gatekeepers of acceptable discourse" in the USA. No way would a major pop singer be allowed to release anything like this today. There are still plenty of acceptable cultural targets of mockery, but this one would today be verboten.
It was a moonlit night in old Mexico
I walked alone, between some old adobe haciendas.
Suddenly, I heard the plaintive cry of a young Mexican girl....
La-la-la! La-la-la-la-la-la-la-laaa! etc.
You better come home, Speedy Gonzales
Away from Tannery Row
Stop all of your drinkin'
With that floozie named Flo
Come on home to your adobe
And slap some mud on the wall
The roof is leakin' like a strainer
There's loads of roaches in the hall
La-la-la-la!
Speedy Gonzales (Speedy Gonzales)
Why don't you come home?
Speedy Gonzales (Speedy Gonzales)
How come you leave me all alone?
Hey, Rosito, I hafta go shopping downtown for my "mudder"
She needs some tortillas and chili "paypers"
Your doggy's gonna have a puppy
And we're runnin' outta coke
No enchiladas in the icebox
And the television's broke
I saw some lipstick on your sweatshirt
I smelled some perfume in your ear
Well, if you're gonna keep on messin'
Don't bring your business back-a-here
Speedy Gonzales (Speedy Gonzales)
Why don't you come home?
Speedy Gonzales (Speedy Gonzales)
How come you leave me all alone?
Hey, Rosita come quick! Down at the cantina
They're giving green stamps with tequila!!
