I am not entirely certain, but I believe that is one of the versions of the song Tico Tico, originally known as Tico Tico no Farela and then later as Tico Tico no Fuba. It was written in 1917 by Zequinha de Abreu. There are currently 61 versions of this song as far as I know.
Yes, that's it. Tico Tico made its first appearance in the States in a Disney cartoon short with Donald Duck, which was the usual dreck propaganda about the "happy people of Latin America."
The clue: "An obscure hint: The song title is twice as nice," referred to the fact the song was called "Tico Tico."
There are actually more than 100 versions of this song, but 61 of them were collected and published on
WFMU's Blog, where you can download and listen to all of them if you like.
The English Lyrics are:
Oh tico-tico tick! Oh tico-tico tock! This tico-tico - he's the cuckoo in my clock. And when he says: "Cuckoo!" he means it's time to woo; It's "tico-time" for all the lovers in the block. I've got a heavy date - a tete-a-tete at eight, so speak, oh tico, tell me is it getting late? If I'm on time, "Cuckoo!" but if I'm late, "Woo-woo!" The one my heart has gone to may not want to wait!
For just a birdie, and a birdie who goes no-where, He knows of ev'ry Lovers' Lane and how to go there; For in affairs of the heart, my Tico's terribly smart, He tells me: "Gently, sentiment'ly at the start!"
Oh-oh, I hear my little tico-tico calling, Because the time is right and shades of night are falling. I love that not-so-cuckoo cuckoo in my clock: tico-tico tico-tico-tico tock!
This version was recorded by Percy Faith & His Orchestra.
