3) Who is more likely to have made these songs - city dwellers working under conveyor belt conditions or country dwellers responding to what was happening all around them?

We have already addressed this one numerous times. Vic just addressed the 'conveyor belt' idea. I certainly haven't given the impression (at least I hope so) that this was some sort of conveyor belt. I've already stated that from what we know of the writers they came from a variety of backgrounds and had various motives, admittedly the 2 most obvious, to feed a family and to feed a drink habit. We've also repeatedly asked you to give some examples of songs that couldn't have been written by the urban writers.
