Actually, I think Harker makes few accusations of 'fakery'; maybe his target is 'inaccurate' or 'politically incorrect' or 'selective' (in his view) representations of working class culture/ He also seems to me to be sparing in suggesting 'appropriation' of working class culture, something else that people say is a theme of his. I expected a lot more on this subject. But this sparsity maybe because in many cases he doubts whether the material that people were printing actually did originate with the working class/lower strata of society/peasants. You cannot appropriate from the working class culture which wasn't working class to start with. A few times I found him saying, in effect, 'X printed these songs, some of which may have come from working class culture'. So a person who took a strong 'all these brilliant songs were definitely written by the working class' view would get pretty annoyed with Harker? Is what I am saying the ideas others are getting from reading him?
