Lyrics:

Hey I'm just an old chunk of coal
But I'm gonna be a diamond some day
I'm gonna grow and glow till I'm so blue pure perfect
I'm gonna put a smile on everybody's face
I'm gonna kneel and pray every day
Lest I should become vain along the way
I'm just an old chunk of coal now Lord
But I'm gonna be a diamond some day

I'm gonna learn the best way to walk
Gonna search and find a better way to talk
I'm gonna spit and polish my old rough edged self
Till I get rid of every single flaw
I'm gonna be the world's best friend
Gonna go round shaking everybody's hand
I'm gonna be the cotton pickin' rage of the age
I'm gonna be a diamond some day

I'm just an old chunk of coal
But I'm gonna be a diamond some day
