Sung by Debbie Reynolds and Carlton Carpenter in 'Two Weeks with Love,' a 1950 musical.

Chorus goes:

Abadabadabadabadaba said the monkey to the chimp
Abadabadabadabadaba said the chimpy to the monk
All day long they'd frolic and play
All day long they were happy and gay
singing and swinging in the abadaba way
badabadabadabadaba means monk I love but you
Abadabadaba in monkey talk means chimp I love you too
And the big baboon one night in June
He married them and very soon
They went upon an abadaba honeymoon
