When the late Tennessee Ernie Ford sang about the drudgeries of loading sixteen tons, his managers, close confidants and friends stated that he was clearly singing about loading by hand a back to back angle iron self supporting tower onto a flatbed. Then the historical revisionists came along without portfolio and said that there might be a gossamer of truth in the rumor that the weighty shipment was coal. Unbelievable! It's amazing what depths the energy titans will sink to in promoting their industry.
