Not again, again, again, again...…………..!

Absolutely, the 90% includes many examples from an earlier period than the early 19thc. We've given plenty on this very thread. The broadside still remains the earliest extant example even in these cases.

This must have now been said numerous times by many on this thread and others similar. NO-ONE has claimed at any point that country people were incapable of making their own songs or indeed that they didn't make their own songs. On the contrary I have given you plenty of examples from my own experiences. All we have said is that not having easy access to the printers their efforts by and large were not widespread around the country and stayed in their own backyard. Simple logic can tell you this. This is why relatively few of their productions made it into the national corpus.

Your last statement no-one can argue with. Most of the evidence is circumstantial and your opinion is perfectly valid, based upon little research into the other printed material however.
