somewhere overt和rainbow

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?
When our world is whole blessed jumbo
And the rain drops tumble
Over round
Heaven opens a magic lane
Whenever the clouds ducking up the skyway
Thats rainbow have waited to be flown
from your window
Truth are places behind the sun
Just stand behind the rainbow
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 ?
