(I'm just an) old chunk of coal

[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
