Here's a little song I 
You might want to sing it note  note
Don't worry, be happy.
 every life we have some trouble
But  you worry you make it double
Don't worry, be happy.
Don't worry, be happy now.
(Chorus)
Don't worry, be happy. Don't worry, be happy.
Don't worry, be happy. Don't worry, be happy.
Ain't got no place to lay your head
Somebody  and   your bed
Don't worry, be happy.
The landlord say your rent is late
He  have to litigate
Don't worry, be happy.
(Chorus)
(Look  me -- I'm happy. Don't worry, be happy.
Here I give you my phone number. When you worry, call me,
I make you happy. Don't worry, be happy.)
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 everybody 
Don't worry, be happy.
(Chorus)
(Don't worry, don't worry, don't do it.
Be happy. Put a smile  your face.
Don't bring everybody down like this.
Don't worry. It will soon pass, whatever it is.
Don't worry, be happy.
I'm not worried, I'm happy...)
