There's a rainbow round my shoulder
And a sky of blue above
How the sun shines bright
The world's all right
Cause I'm in love

There's a rainbow round my shoulder
And it fits me like a glove
Let it blow let it storm, I'll be warm
'Cause I'm in love

Hallelujah, how the folks will stare
When they see that solitare
That my little baby is gonna wear

There's a rainbow round my shoulder
And a sky of blue above
And I'm shoutin so the world
Will know that I'm in love

Hallelujah, how the folks gonna stare
When they see that diamond solitare
That my own true baby's gonna wear

There's a rainbow round my shoulder
And a sky of blue above
And I'm shoutin so the world
Will know

I'm in love, I'm in love
There's a rainbow round my shoulder
And I'm in love
