"I'm Just an Old Chunk of Coal (But I'm Gonna Be a Diamond Someday)" was written and originally recorded by Billy Joe Shaver, but became a big hit (#4 on the charts) when John Anderson released it.
But that raises the question, "How long does it take for coal to form?" In the early 1980's chemists at Argonne National Laboratory created artificial coal from naturally occurring materials. They demonstrated that the coal formation process was much less severe than formerly thought.
E.A. Newell Arber (d. 1918) was a Professor at the University of Cambridge with a focus in paleobotany and wrote The Natural History of Coal. Arber concluded that the close association of some coal seams with sandstones, shales and conglomerates provides "evidence of the rapid formation of coal." 
Many scientists have a bias against Young Earth Science (YES). This is also common among academics and journalists. CatherineBennett wrote a piece in the Guardian titled "The BBC’s fixation on ‘balance’ skews the truth" where she showed disrespect for the young earth viewpoint.
In contrast, Melvin Bragg (Chancellor of the University of Leeds) hosted a BBC radio program on the Age of the earth.  Several comments supported YES. There were apparently seven who favored YES and seven who agreed with the Old Earth view. Is the BBC pro-YES? Maybe not, but at least they gave the YES advocates an opportunity to argue their case.
I hope Catherine Bennett gets a copy of my book YES - Young Earth Science which defends a youthful world from history and science. YES, you can even get it from Wal-Mart (online).
