One of those should have been forgotton songs, but it's crawling in my ear:

FLYING DOWN TO RIO
Vincent Youmans, Gus Kahn, Edward Eliscu

An old sailor in old time sing an old song
Rolling down to Rio by the sea
A young sailor in these times
Would sing a new song
Flying down to Rio, come with me.

Where the lovely Brazilian ladies
Will catch your ride
By the light of the million stars
In the evening sky.

My Rio, Rio by the sea-o,
Flying down t Rio where there's rhythm and rhyme.
Hey, feller, twirl that old propeller
Got to get to Rio and we've got to make time.
Oh, Rio, you'll love it, soaring high above it,
Looking down on Rio from a heaven of blue.

Send a radio to Rio de Janiero,
With a big hello just so they'll know and stand by there,
We'll fly there.
Hey, Rio, everything will be okay,
We're singing and winging our way to you.

Dolores del Rio, Gene Raymond, Ginger Rogers, Fred Astaire, who else?

Charley, let's see you make a chantey out of that! Or try "Carioca."
