ok! found my song. :)

[scottobear]

Here's a little song I wrote
You might want to sing it note for note
Don't worry, be happy
In every life we have some trouble
When you worry you make it double
Don't worry, be happy
Don't worry, be happy now

{Refrain}
Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be happy
Oo-oo-oo-oo-oo
Don't worry, be happy

{Refrain}

Ain't got no place to lay your head
Somebody came and took your bed
Don't worry, be happy
The landlord say your rent is late
He may have to litigate
Don't worry, be happy
Look at me, I'm happy

{Refrain}
Give you my phone number
When you worry, call me, I make you happy

{Refrain}

Ain't got no cash, ain't got no style
Ain't got no gal to make you smile
But don't worry, be happy
'Cause when you worry, your face will frown
And that will bring everyody down
So don't worry, be happy
Don't worry, be happy now

{Refrain}

{Refrain}

Now there, is this song I wrote
I hope you learned it note for note
Like good little children
Don't worry, be happy
Listen to what I say
In your life expect some trouble
When you worry you make it double
Don't worry, be happy, be happy now
