Lyrics Let's Do It - Live - Ella Fitzgerald

Birds do it, bees do it
Even educated fleas do it
Let's do it, let's fall in love
In Spain, the best upper sets do it
Lithuanians and Letts do it
Let's do it, let's fall in love
The Dutch in old Amsterdam do it
Not to mention the Fins
Folks in Siam do it - think of Siamese twins
Some Argentines, without means, do it
People say in Boston even beans do it
Let's do it, let's fall in love
Romantic sponges, they say, do it
Oysters down in oyster bay do it
Let's do it, let's fall in love
Cold Cape Cod clams, 'gainst their wish, do it
Even lazy jellyfish, do it
Let's do it, let's fall in love
Electric eels I might add do it
Though it shocks em I know
Why ask if shad do it - Waiter bring me
"Shad roe"
In shallow shoals English soles do it
Goldfish in the privacy of bowls do it

Let's do it, let's fall in love
Transcribed (from the stated recording) by Todd Peach
Other verses I've seen in print follow:
In old Japan, all the Japs do it
Up in Lapland little Laps do it
Let's do it, let's fall in love
The chimpanzees in the zoos do it
Some courageous kangaroos do it
Let's do it, let's
Fall in love
I'm sure giraffes on the sly do it
Even eagles as they fly do it
Let's do it, let's fall
In love
Electric eels I might add do it
Though it shocks em I know
Why ask if shad do it - garcon de
"Shad roe"
The world admits bears in pits do it
Even Pekingeses at the Ritz do it
Let's do it, let's
Fall in love
The royal set sans regret did it
And they considered it fun
Marie Antoinette did it -
With or without Napoleon
