Lyrics:

[Verse]
I'm just an old chunk of coal
But I'm going to be a diamond some day
I'm going to grow and glow
Until I'm so blue pure perfect
I'm going to put a smile on everybody's face
But I'm going to 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 going to be a diamond some day
I'm going to be learn the right way to talk
I'm going to search and find a better way to walk
I'm going to spit and polish my old rough-edged self
Until I get rid of every single flaw
I'm going to be the world's best friend
I'm going to be go around shaking everybody's hand
I'm going to be the cotton-picking Rage of the Age
Yes I'm going to be a diamond some day

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