@ Brian Peters:

We discussed Poverty Knock in 2010:

Poverty Knock Thread

While some people say that Tom Daniel wrote the song, I think it's fairer to say that he more likely re-adapted it, or "rescued" it.

I definitely remember my mum singing bits of it in the 1950s and her and her sisters could sing it straight off when it first came on the radio. They remembered singing versions of it in Popplewell Mill near Cleckheaton (very close to Batley where TD worked) in the 1930s.

So I think that one may be a bit of a red herring, unlike, say, Fiddler's Green, Shoals of Herring, Safe Harbour Tonight, etc, where we know with 100% certainty who wrote them and when.
