La vida est asi (that's the way life is).

It's by Frank Loesser. It is from the movie _Tortilla Flat_, after John Steinbeck's book of the same name. I have never managed to see it.

AI, AI, PAISANO!
(Frank Loesser)

I love Torelli, he's a friend of mine,
I love Torelli, I love him for his wine,
He's got my watch, his wine is in my belly,
If it was not for the wine, I would not love Torelli.
Ai, Ai, Paisano! La vida es asi.

You love Torelli, now that's a funny joke,
If Torelli was on fire he wouldn't give you smoke,
Not that I'm so handsome, but my eyes they have a shine,
If it was not for his wife, we would not get much wine.
Ai, Ai, Paisano! La vida es asi.

Listen amigos, I will ask you this,
Why is a glass just like a woman's kiss?
When it's full of wine it makes you blind a little bit,
When the wine is gone, you can see through it!
Ai, Ai, Paisano! La vida es asi.

I know a lady named Arabella Gross,
I know her, and you know her, but I know her the most.
When I drink a little drink, I make a little toast,
To your friend and my friend, Arabella Gross.
Ai, Ai, Paisano! La vida es asi.

Mrs. Morales got chickens in her yard,
If you'd like to get one it isn't very hard,
Smile for the senora, you'll get one for free,
If Danny feels like smiling nice, he'll get two or three.
Ai, Ai, Paisano! La vida es asi.

Danny is a lucky boy, I'm a friend of his,
I'm the one who saved him from a wife, and goats and cheese,
I give him all my good advice for only half his wine,
Danny is a lucky boy, he's a friend of mine.
Ai, Ai, Paisano! La vida es asi.

Oh you little squid, you ugly little squid,
I promised I would go to work, and that is what I did,
Oh you little squid, you homely little squid,
I bet your Mama thinks that you're a pretty kid.
Ai, Ai, Paisano! La vida es asi.

The old MIT Outing Club songbook has it, with some differences in detail (including the Yips) & the last two stanzas missing. The same version may be found in
