Letras:Dean Martin. Chee Chee-oo Chee.

(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
Once on a tree top tall a little bird
(Chee-chee oo chee, chee-chee oo chee)
Sang out the sweetest song I ever heard

(Chee-chee oo chee, chee-chee oo chee)
He sang to me so merrily
(Chee-chee oo chee, chee-chee oo chee)
The little birdie on the tree

Life's such a lovely thing it seemed to say
(Chee-chee oo chee, chee-chee oo chee)
If you'd only sing your cares away
(Chee-chee oo chee, chee-chee oo chee)
Chee chee-oo chee so merrily it went along

(Chee-chee oo chee, chee-chee oo chee)
Chee chee-oo chee so happily his little song
(Chee-chee oo chee, chee-chee oo chee)

And so
(And so)
I sing
(I sing)
Chee-chee oo chee, the happy happy little thing

If you
(If you)
Feel blue
(Feel blue)
Sing chee-chee oo chee and you can be as happy too

(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
Sing this happy little song

(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
Chee-chee oo chee

Chee-chee oo chee, it sang to me so merrily
(Chee-chee oo chee, chee-chee oo chee)
Chee-chee oo chee, the little birdie on the tree
(Chee-chee oo chee, chee-chee oo chee)

(If you feel blue)
Sing chee-chee oo chee, chee-chee oo chee
And you can be as happy, too

(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
(Chee-chee oo chee, chee-chee oo chee)
Sing this happy little song

(Sing chee chee-oo chee, chee chee-oo chee
And you can be as happy as can be)
