Her name was Lola, she was a showgirl

HER NAME WAS LOLA, SHE WAS A DANCER

With yellow feathers in her hair and a dress cut down to there

WITH YELLOW FEATHERS IN HER HAIR AND A DRESS THAT SHOWED HER BREASTS (seios, nao pernas)

She would merengue and do the cha-cha

SHE WOULD DANCE THE MERENGUE AND THE CHA-CHA

And while she tried to be a star, Tony always tended bar

AND WHILE SHE TRIED TO BE A STAR, TONY ALWAYS WORKED AT THE BAR

Across a crowded floor, they worked from 8 till 4

SHE WORKED ON ONE SIDE OF A ROOM FULL OF PEOPLE AND HE ON THE OTHER SIDE FROM 8:00 PM UNTIL 4:00 AM

They were young and they had each other

THEY WERE YOUNG AND IN LOVE

Who could ask for more?

WHO COULD ASK FOR MORE?

At the Copa (CO!), Copacabana (Copacabana)
The hottest spot north of Havana (here)
At the Copa (CO!), Copacabana
Music and passion were always the fashion
At the Copa....they fell in love

(Copa Copacabana)

His name was Rico, he wore a diamond

HIS NAME WAS RICO, HE HAD A DIAMOND (ring?  on his tie?)

He was escorted to his chair, he saw Lola dancin' there

SOMEONE TOOK HIM TO HIS CHAIR, HE SAW LOLA DANCING THERE

And when she finished, he called her over

AND WHEN SHE STOPPED DANCING, HE INVITED HER TO HIS TABLE

But Rico went a bit too far, Tony sailed across the bar

BUT RICO SAID/DID SOMETHING INAPPROPRIATE, TONY QUICKLY JUMPED OVER THE BAR (as if he were an airplane)

And then the punches flew and chairs were smashed in two

AND THEN THE FIGHT STARTED AND CHAIRS WERE BROKEN INTO TWO PIECES

There was blood and a single gun shot

THERE WAS BLOOD AND A GUN FIRED ONCE

But just who shot who?'

BUT WHO SHOT WHOM?  ("just" is for emphasis and adds nothing to the sentence)
