The song, as I remember, was sung by Carmen Miranda, Donald Duck, and Jose Carioca (the last two animated, obviously). What I remember is:

Cuanto la gusta, la gusta, la gusta, la gusta, la gusta, la gusta
Repeat
When are we leavin', Where are we goin', What are we gonna do.
We're on our way to somewhere, the three of us and you.
What'll we see ther, when will we be there, what'll be the big surprise.
We're headin' South tomorrow with starlight in our eyes.
We're on our way, we won't be back. And if we stay, we won't be back.
How can we go ? We haven't got a dime.
But we're goin' and we're gonna have a happy time.
Cuanto la gusta, la gusta, etc.

Enjoy !! Les
