DESCRIPTION:
Great song from a great movie. Slightly different version than the one used in the film. Taken from the vinyl LP "Songs from 'Broadway Danny Rose' and other Pearls of Culture".

I put up an instrumental version from the movie, too:

If you want to play along, here's a chord tab for the song:

And this is a corrected version of what I understood from the lyrics (thanks a lot to miccar2005):

Agita, my goombah in the panzon
When I eat he gets a treat like a canzon
He enjoys every meal, every bite that I steal
Agita, my cumpà in the panzon

Some people like their pizza
Some people like a soffritt
And others like hot pepper
On everything they eat
You hunger with a vuole
To taste some baccalà
And all of once you think
"Well, I answer to cumpà"

My lovely, lovely woman
I hate to see her cry
But when I start to mangia
I get the evil eye
My vuole's getting stronger
Ah, to hell with my cumpà
Then I get it from my woman
Che te pozzan' schiattà

Agita, my goombah in the panzon
When I eat he gets a treat like a canzon
He enjoys every meal, every bite that I steal
Agita, my cumpà in the panzon

The tasty veal and peppers
With linguin' by the side
I know it gets confusing
You just cannot decide
But if you cross your cumpà
There is not a place to hide
So think about la panza
With that little man inside

Agita, my goombah in the panzon
When I eat he gets a treat like a canzon
He enjoys every meal, every bite that I steal
Agita, my cumpà in the panzon
Agita, my cumpà in the panzon
