I'm Always Chasing Rainbows

At the end of the rainbow, there's happinessAnd to find it how often I've triedBut my life is a racejust a wild goose chaseand all my dreams have been deniedWhyh ave I always been a failureWhat can the reason beI wonder if the world's to blameI wonder if it could be meI'm always chasing rainbows, watching clouds drifting byMy schemes are just like all my dreamsending in the skySome fellows look and find the sunshineI always look and find the rainAnd some fellows make a winning sometimeand I never even make a gainI'm always chasing rainbows waiting to find the little bluebird in vain.
