WEEKEND OF A PRIVATE SECRETARY
(Johnny Mercer, Bernie Hanighen, 1938)

I went to Havana
On one of those cruises
For forty-nine fifty,
To spend a few days.
I went to Havana,
To look at the natives,
To study their customs,
Their picturesque ways.

In searching for some local color,
I ran across a Cuban gent;
And he was such a big sensation,
I forgot the population.

He showed me the city,
He taught me the customs;
My trip to Havana
Was quite a success.

We had Bacardi;
I forgot the clock,
So we were tardy
In returning to the dock.

Though' I delayed it,
Even dropped my shawl,
The Cuban made it
As they gave the final call.
Darn it all!

I'm back in the office,
I'm punching the time clock;
But you can bet my mind
Is not on my work.
Instead of Bacardis,
I'm ordering Bromos,
Instead of the Cuban
I'm stuck with a clerk.

The other girls can go to Europe
And marry into royalty,
And they can get an Earl or Pasha
Or a gent with lots of cash-a…

But when I get married
And settle in Brooklyn,
He may be a slicker,
He may be a hick or a Ruben,
But you can bet that he'll be Cuban.
Si, si, si!
