The one I remember at the end goes
Happy birthday to you
All the monkeys
In the Zoo give their best regards to you
Happy birhday to you.
I went on up to the Audubon Zoo
And they only asked for you
They all asked for you
Well, even inquired about you
I went on up to the Audu'mon Zoo
And they all asked for you
The monkey's asked
The tiger's asked
And the elephant asked f'you, too
