In my head I hear Puggy McFerrin:
"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
But when you worry you make it double
Don't worry be happy
Don't worry be happy now
Ooh-ooh-hoo-hoo-ooh hoo-hoo-ooh-ooh ooh
Don't worry
Woo ooh-woo-ooh-woo-ooh-ooh
Be happy"
