In the film, The Man With Two Brains, what are the lyrics to the song Steve Martin sings?

Question

It begins 'If I love-a-you and you love-a-me.....'
Does anyone know the rest of the words? Thanks.

Answer 1

"Under the Bamboo Tree"
Words and Music by Bob Cole and J. Rosamund Johnson

Verse 1
Down in the jungles lived a maid,
Of royal blood though dusky shade,
A marked impression once she made,
Upon a Zulu from Matabooloo;
And ev'ry morning he would be
Down underneath the bamboo tree,
Awaiting there his love to see
And then to her he'd sing:

Chorus
If you lak-a-me lak I lak-a-you
And we lak-a-both the same,
I lak-a-say,
This very day,
I lak-a change your name;
'Cause I love-a-you and love-a you true
And if you-a love-a me.
One live as two, two live as one,
Under the bamboo tree.

Verse 2
And in this simple jungle way,
He wooed the maiden ev'ry day,
By singing what he had to say;
One day he seized her
And gently squeezed her.
And then beneath the bamboo green,
He begged her to become his queen;
The dusky maiden blushed unseen
And joined him in his song.

Chorus
If you lak-a-me lak I lak-a-you
And we lak-a-both the same,
I lak-a-say,
This very day,
I lak-a change your name;
'Cause I love-a-you and love-a you true
And if you-a love-a me.
One live as two, two live as one,
Under the bamboo tree.

Verse 3
This little story strange but true,
Is often told in Mataboo,
Of how this Zulu tried to woo
His jungle lady
In tropics shady;
Although the scene was miles away,
Right here at home I dare to say,
You'll hear some Zulu ev'ry day,
Gush out this soft refrain:

Chorus
If you lak-a-me lak I lak-a-you
And we lak-a-both the same,
I lak-a-say,
This very day,
I lak-a change your name;
'Cause I love-a-you and love-a you true
And if you-a love-a me.
One live as two, two live as one,
Under the bamboo tree.

Is that the one where he's singing in the bathtub?
"I'm picking out a thermos for you"
