I'm Always Chasing Rainbows

At the end of the rainbow there's happiness,
And to find it often I've tried,
But my life is a race, just a wild goose chase,
And my dreams have all been denied.
Why have I always been a failure?
What can the reason be?
I wonder if the world's to blame,
I wonder if it could be me.
Chorus:
I'm always chasing rainbows,
Watching clouds drifting by,
My schemes are just like all my dreams,
Ending in the sky.
Some fellows look and find the sunshine,
I always look and find the rain.
Some fellows make a winning sometime,
But I never even make a gain, believe me,
I'm always chasing rainbows,
Waiting to find a little bluebird in vain.
