[Verse 1]
I'm just an old chunk of coal
But I'm gonna be a diamond someday
I'm gonna grow and glow
'Til I'm so blue pure perfect
I'm gonna put a smile on everybody's face
But I'm gonna kneel and pray everyday
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 someday

[Verse 2]
I'm gonna learn the right way to talk
I'm gonna search and find a better way to walk
I'm gonna spit and polish my old rough-edged self
Until I get rid of every single flaw
I'm gonna be the world's best friend
I'm gonna go 'round shaking everybody's hand
I'm gonna be the cotton-pickin' rage of the age
Yes, I'm gonna be a diamond some day

[Outro]
I said, I'm just an old chunk of coal, now, Lord
But I'm gonna be a diamond some day
