cilla black
i can sing a rainbow
red and yellow and pink and green
orange and purple and blue
sing a rainbow
sing a rainbow too
listen with your eyes
and sing everything you see
you can sing a rainbow
sing along with me
the sun is yellow
the grass is green
look how the sky is blue
we can sing a rainbow
surely you can too
the sky is black
the clouds are white
and it's raining too
but we can sing a rainbow
sing a rainbow of happiness for you
