overt和rainbow

Somewhere over the rainbow way up high
There's 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
One day I'll wish upon a star
And wake up where the clouds are far behind me
Where your troubles melt like lemon drops
Way above the chimney tops, that's where you'll find me
Oh, somewhere over the rainbow bluebirds, they fly
If birds can fly over, over the rainbow, why, then why can't
I?One day
I'll wish upon a star
And wake up where the clouds are far behind me
Where your troubles melt like lemon drops
Way above the chimney tops, that's where you'll find me
Oh, somewhere over the rainbow bluebirds, they fly
If birds can fly over the rainbow, why, then why can't
I?If happy little bluebirds fly beyond the rainbow
Why, oh, why can't
I?
