When I feel blue, I feel blue, I feel blue
What do I do, do I do, do I do?
I just start singing the happiest song in the world...La!

Singing this song, ing this song, ing this song
Nothing is wrong, ing is wrong, ing is wrong
Not when I'm singing the happiest song in the world...La!

Happy happy happy happy happy happy happy happy happy happy happy happy happy happy happy happy Song!

Now we are singing the happiest song in the world...La!

Happiest song in the happiest song in the happiest song in the happiest song in the world
Oh Oh Oh Oh!
