[Intro]
When the little blue bird who has never said a word starts to sing, "Spring, spring"
When the little bluebell in the bottom of the dell starts to ring, "Ding-ding"
When the little blue clerk in the middle of his work starts a tune to the moon up above
It is nature, that's all, simply telling us to fall in love

[Verse 1]
And that's why birds do it, bees do it
Even educated fleas do it
Let's do it, let's fall in love

[Verse 2]
In Spain, the best upper sets do it
Lithuanians and Letts do it
Let's do it, let's fall in love

[Bridge 1]
The Dutch in old Amsterdam do it
Not to mention the Finns
Folks in Siam do it
Think of Siamese twins

[Verse 3]
Some Argentines without means do it
People say in Boston even beans do it
Let's do it, let's fall in love
[Interlude]
Take it, Brian
Mm, mm, yeah

[Bridge 2]
Electric eels, I might add, do it
Though it shocks 'em, I know
Why ask if shad do it?
Waiter, bring me shad roe

[Verse 4]
In shallow shoals, English soles do it
Goldfish in the privacy of bowls do it
Let's do it, let's fall in love
Let's do it, let's fall in love
