Somewhere over the rainbow
way up high
Theres a land that I heard of
once in a lullaby
Somewhere over the rainbow
skies are blue
And the dreams that you dare to dream
really do come true
Someday Ill wish upon a star
And wake up where the clouds are far behind me
Where troubles melt like lemon drops away above the chimney tops
Thats where youll find me
Somewhere over the rainbow
bluebirds fly
Birds fly over the rainbow, why then
oh why cant I?
Somewhere over the rainbow
bluebirds fly
Birds fly over the rainbow
why then oh why cant I?
If happy little bluebirds fly beyond the rainbow
Why oh why cant I?
