Ruth, as one whose politics are dead center (no pun intended) I never got a sense from the songs themselves that I was being manipulated - though I admit I haven't listened much to Lloyd's industrial songs, "Blackleg Miner" being the most obvious exception.
Songs like "Do Me Ama" and "Reynardine" and even "The Weaver and the Factory Maid" come off as humanistic rather than propagandist documents.

Lloyd's unacknowledged manipulation of his material is ridiculously low on the scale of human wrongdoing. The truth remains that he often misrepresented facts of tradition when he knew better.

Which has costs for folksong scholarship.
