"On a quick revisit, most of the songs in the collection are as unsingable as is the vast majority of the broadside repertoire
As with all song collections, the proof of the pudding..."(JC)

Why bother revisiting however quickly? No-one is contesting the FACT that the vast majority of stuff that appeared on broadsides is as you say it is. But there was obviously enough in there to please some members of the population, enough for it to have gone into oral tradition. Hundreds of thousands of songs of all descriptions and origins were printed on broadsides, so a couple of thousand that made it into oral tradition is just a drop in the ocean. As with most sectors of life, just by the law of averages some of the material will be better than others.

Why are you posting info that everybody is aware of?
