Lyrics of Chunk of coal

I'm just an old chunk of coal
But i'm gonna be a diamond some day
I'm gonna glow and grow
'til i'm so blue pure perfect
I'm gonna put a smile on everybody's face
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 some day

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